A display panel according to an embodiment of the present invention is a display panel having a display region including a plurality of pixels arrayed along a first direction and along a second direction which is different from the first direction, the display panel including a first substrate and a second substrate opposing each other, the first substrate and the second substrate being curved along the first direction. The first substrate has a color filter layer that includes: a plurality of color filters provided respectively corresponding to the plurality of pixels; and a black matrix having a plurality of light shielding portions disposed between adjacent color filters adjoining along the first direction. The second substrate includes a plurality of pixel electrodes respectively included in the plurality of pixels. The display region includes a central portion including a center of the display region along the first direction and, on both sides of the central portion along the first direction, a first end portion and a second end portion that are located adjacent to the central portion. The plurality of pixels include a plurality of central pixels contained in the central portion and a plurality of end pixels contained in the first end portion or the second end portion. The plurality of light shielding portions include a plurality of central light shielding portions contained in the central portion and a plurality of end light shielding portions contained in the first end portion or the second end portion. A width of the plurality of end light shielding portions along the first direction is greater than a width of the plurality of central light shielding portions along the first direction.

Display panel and display panel apparatus

A light guide member has a plurality of optical fibers extending from a light receiving surface to a light emitting surface, and an extension part formed on the light emitting surface extending laterally, with respect to the light receiving surface, in a width direction. At least one part of the plurality of optical fibers is configured that the dimension of each optical fiber in the width direction is greater on the light emitting surface than the light receiving surface. The light guide member is configured to be provided on the outer periphery of at least two adjacent display panels to reduce non-display areas of a multi-display arrangement.

Display apparatus having light guide member with tapered optical fibers

To provide a display device whereby luminance distribution uniformity within a display surface can be improved. A display device of the present invention is provided with: a rectangular display panel, one surface of which displays an image; a substrate, which is disposed to face the other surface of the display panel, said the other surface being on the reverse side of the one surface, and on which a plurality of light sources are mounted; a diffuser plate disposed between the display panel and the substrate; and a supporting member, which has an opening, which light emitted from the light sources passes through, and which supports the peripheral end of the diffuser plate. The display device is also provided with reflecting members, which are respectively provided at the peripheries of the light sources close to four corner portions of the display panel, and which reflect light diffused by the diffuser plate to the corner portions of the display panel.

Display device

Image display

Provided is a display device that makes it possible to enhance the uniformity of brightness distribution with a display surface. The display device is provided with: a display panel having one surface on which an image is displayed; a substrate that is arranged facing the other surface of the display panel and that has a plurality of light sources mounted thereon; a rectangular diffuser plate arranged between the display panel and the substrate; and two support members that comprises an opening through which light from the light sources passes and that support the diffuser plate by sandwiching the peripheral edge of the diffuser plate from the display panel side and the substrate side. Light-transmitting sections through which light that has passed through the diffuser plate passes are provided to the four corners of the support member on the display panel side.

A display apparatus has a display panel having a display region, a light shielding region surrounding the display region, and an outer region located outside of the light shielding region; a support frame disposed at a rear surface side of the display panel, the support frame including a panel supporting portion which supports a peripheral portion of the display panel from a rear side, and an extension beginning from the panel supporting portion and extending away from the display panel; and a light shield disposed at the rear surface side of the display panel, the light shield including a light-shielding portion which is disposed between the display panel and the support frame, the light-shielding portion extending so as to overlap at least a portion of the light shielding region and the outer region of the display panel as viewed from a normal direction of the display panel, and a fixture portion beginning from the light-shielding portion and extending away from the display panel, the fixture portion being fixed to the extension of the support frame.

Display apparatus

Provided is a display device wherein the uniformity of luminance distribution on a display surface can be improved. The display device includes: a rectangular display panel on one surface of which an image is displayed; a substrate disposed to face the other surface of the display panel opposite to the one surface, and having a plurality of light sources mounted thereon; a diffuser disposed between the display panel and the substrate; and a supporting member supporting the peripheral edge of the diffuser, and having an opening through which light from the light sources passes. The display device further includes a reflecting member provided around each of the light sources close to the four corners of the display panel, and reflecting the light from the light sources toward the corners.

Provided is a display device that makes it possible to enhance the uniformity of brightness distribution within a display surface. The display apparatus is provided with: a display panel having one surface on which an image is displayed; a substrate that is arranged facing the other surface of the display panel and that has a plurality of light sources mounted thereon; a rectangular diffuser plate arranged between the display panel and the substrate; and a support member that supports the peripheral edge of the diffuser plate and that comprises an opening through which light from the light sources passes. Notched sections notched to positions further inward than the edge of the opening in the support member are provided to the four corners of the diffuser plate.

Display

Provided are a light source device which includes a light guide plate configured to emit light made incident thereon through one surface thereof, a reflection sheet which has one surface facing the other surface of the light guide plate and is configured to reflect the light made incident on the light guide plate to one surface side of the light guide plate, and an opposite member oppositely disposed to the other surface of the reflection sheet, such that an occurrence of wrinkles and deflection in the reflection sheet may be prevented with a simple configuration, while surely fixing the position of the reflection sheet, and a display apparatus including the light source device. The reflection sheet includes a first reflection sheet piece and a second reflection sheet piece, wherein the first reflection sheet piece is pinched by the light guide plate and the back cover, and the second reflection sheet piece is held by the first reflection sheet piece.
