A display device includes a pixel circuit, a first insulation layer covering the pixel circuit, a first electrode disposed on the first insulation layer, a second electrode disposed on the first insulation layer while being spaced apart from the first electrode, a second insulation layer covering the first electrode, the second electrode, and the first insulation layer disposed between the first electrode and the second electrode, and a light emitting element electrically connected to the first electrode and the second electrode on the second insulation layer and disposed between the first electrode and the second electrode. Here, the second insulation layer includes a first area overlapping the first electrode, a second area overlapping the second electrode, and a stopper area disposed between the first electrode and the second electrode, and the stopper area has a thickness different from that of each of the first area and the second area.

Display device and method of manufacturing the same

A backlight unit includes a light source part configured to emit a light and a reflective sheet disposed under the light source part. The light source part includes a first light source block including a plurality of light sources with first distances therebetween and a second light source block including a plurality of light sources with second distances therebetween. The first distances increase or decrease as the light sources of the first light source block are closer to an end portion of the first light source block than to a center portion of the first light source block, and the second distances increase as the light sources of the second light source block axe closer to an end portion of the second light source block than to a center portion of the second light source block.

Backlight unit and display device having the same

A display device includes first light emitting devices arranged in a line in a protective member, second light emitting devices parallel to and alternately arranged with the first light emitting devices, and optical member supporters in the protective member between the first and second light emitting devices. Each optical member supporter is positioned at a center of a parallelogram defined by two adjacent first light emitting devices and two adjacent second light emitting devices, and each transparent optical member supporter includes a first surface that faces one of the first light emitting devices and a second surface opposite the first surface that faces one of the second light emitting devices. Each optical member supporter includes a plate portion having the first and second surfaces, and a hook portion that extends through the protective member. A width of the plate portion decreases with increasing distance from the hook portion.

Display device

A display apparatus includes a bottom plate, a mold frame coupled to the bottom plate to define a receiving space, a backlight unit which is configured to be accommodated in the receiving space and generate light; a sliding recess which is defined by portions of the mold frame and exposed to the receiving space, an inlet portion which is defined by the mold frame and bottom plate, and exposes the receiving space and a side portion of the backlight unit accommodated in the receiving space; a side mold which covers the side portion of the accommodated backlight unit exposed by the inlet portion; and a display unit which is on an upper end of the mold frame and configured to receive the light to display an image. The backlight unit is accommodated in the receiving space through the inlet portion and along the sliding recess.

Display apparatus

A liquid crystal display apparatus includes a display panel that displays an image, a backlight unit that provides a light to the display panel, and a frame that accommodates the display panel and the backlight unit. The backlight unit includes a light source that emits the light, a diffusion plate that diffuses the light from the light source, an optical sheet that condenses the diffused light and provides the condensed light to the display panel, and a clip that couples the diffusion plate and the optical sheet.

Liquid crystal display apparatus

A backlight unit includes a light source which generates light, a light guide plate which guides the light substantially in an upward direction, a first frame member which holds the light source and diffuses the light traveling substantially in the upward direction between the light source and the light guide plate, a second frame member which holds the light guide plate, a third frame member which holds the light guide plate, a reflective plate disposed under the light guide plate and which reflect the light leaked downwardly from the light guide plate substantially to the upward direction, and an optical sheet disposed on the light guide plate and the first to third frame members and which diffuses the light provided from the first frame member and the light guide plate and condenses the light substantially in the upward direction.

A backlight assembly includes a light emitting unit, a reflective sheet, and a bottom cover. The light-emitting unit includes a light source emitting light and an optical system. The optical system is spaced apart from the light source in a direction in which the light emitted from the light emitting unit initially travels. The optical system has a curved shape that reflects a portion of the light emitted from the light source and transmits a remaining portion of the light emitted from the light source. The reflective sheet is disposed under the light-emitting unit to re-reflect the light reflected by the optical system. The bottom cover accommodates the light emitting unit and the reflective sheet. Thus, the light-spreading angle of the light-emitting unit becomes wide.
