A display apparatus includes a liquid crystal panel; a light guide plate behind the liquid crystal panel; a light source adjacent to a thickness surface of the light guide plate and configured to emit light toward the thickness surface of the light guide plate; a rear chassis behind the light guide plate; and a holder coupled to the rear chassis and supporting the light guide plate, wherein the holder includes: a first tooth; a first tooth groove next to the first tooth; a second tooth facing the first tooth; and a second tooth groove next to the second tooth, wherein in a first state, the first tooth is disposed outside the second tooth groove and the second tooth is disposed outside the first tooth groove, and in a second state, the first tooth is inserted into the second tooth groove and the second tooth is inserted into the first tooth groove, and wherein the holder is configured to elastically deform between the first state and the second state.

Display apparatus including a light guide plate holder

A display apparatus includes a liquid crystal panel, a light source configured to provide light to the liquid crystal panel, and an optical member disposed between the liquid crystal panel and the light source. The optical member includes a diffuser sheet that is configured to diffuse the light from the light source, and a deformation preventing layer including a first material having a lower expansion or contraction rate than the diffuser sheet.

Display apparatus

A backlight unit includes a printed circuit board; a light source disposed on the printed circuit board and configured to emit light towards an upper side of the backlight unit; a reflective lens disposed on an upper side of the light source; and a reflective tape attached to the printed circuit board so as to surround the light source. At least a part of the reflective tape has a color different from a color of the light emitted by the light source.

Backlight unit, method of manufacturing the same and display apparatus including the same

Disclosed is a liquid crystal display device including a reflective sheet with high rigidity and low shrinkage and expansion, the liquid crystal display device comprising: a liquid crystal panel; a light guide plate provided below the liquid crystal panel; a light source for supplying light to the light guide plate; a reflective sheet provided below the light guide plate; a glass fiber coating layer provided on the upper surface and/or the lower surface of the reflective sheet; and a lower chassis provided below the reflective sheet.

Liquid crystal display device

A direct type backlight device includes a lower chassis, a reflective sheet disposed on a bottom portion of the lower chassis, and a plurality of light emitting diode (LED) bars disposed on an upper surface of the reflective sheet. Each of the plurality of LED bars includes a bar-shaped printed circuit board disposed on the upper surface of the reflective sheet, a plurality of LEDs disposed on an upper surface of the printed circuit board, and a reflective member provided on the upper surface of the printed circuit board. A reflectance of the reflective member is at least 90% of a reflectance of the reflective sheet.

Direct type back light device and display apparatus having the same

A reflective sheet of a display apparatus includes a sheet configured to reflect light; and a beading pattern protruding from a surface of the sheet.

Reflective sheet and display apparatus having the same

A display apparatus is provided. The display apparatus may include a display panel, an optical member that is disposed behind the display panel and that is configured to guide light to the display panel, a light source that is configured to irradiate light to the optical member, a holder that is configured to support the display panel and the optical member, and a contraction member that is disposed parallel to the optical member, and that comprises a negative thermal expansion (NTE) substance.

A display apparatus is provided. The display apparatus includes a light source, a quantum dot sheet on which a reflective area that reflects light irradiated from the light source and a quantum dot area including a quantum dot that scatters the light irradiated from the light source are alternately disposed, and a display panel that displays an image using light provided from the quantum dot sheet.
