Abstract
A display apparatus including a display panel, a light source unit configured to provide light to the display panel, and a light guide member disposed between the display panel and the light source unit and covering the light source unit such that the light source unit is buried in the light guide member, the light guide member having a surface roughness on an upper surface thereof to diffuse light and including a substrate, and a light emitting device disposed on the substrate and including a blocking pattern to have an intensity of light emitted in an upward direction to be equal to or less than about 80% of a maximum light intensity of the light emitting device.
Claims19
A display apparatus comprising:
- a display panel;
- a light source unit configured to provide light to the display panel;
- and
- a light guide member disposed between the display panel and the light source unit and covering the light source unit such that the light source unit is buried in the light guide member, the light guide member having a surface roughness on an upper surface thereof to diffuse light,
- wherein the light source unit includes:
- a substrate;
- and
- a light emitting device disposed on the substrate and including a blocking pattern to have an intensity of light emitted in an upward direction to be equal to or less than 80% of a maximum light intensity of the light emitting device, and
- wherein the light emitting device comprises:
- a device substrate having a first surface and a second surface;
- a light emitting stacked structure disposed on the second surface;
- and
- a first blocking pattern of the blocking pattern disposed on the first surface.
A backlight unit comprising:
- a light source unit configured to emit light;
- and
- a light guide member disposed on the light source unit and covering the light source unit such that the light source unit is buried in the light guide member, the light source unit having a surface roughness on an upper surface thereof to diffuse light,
- wherein the light source unit includes:
- a substrate;
- and
- a light emitting device disposed on the substrate and including a blocking pattern to have an intensity of light emitted in an upward direction to be equal to or less than 80% of a maximum light intensity of the light emitting device, and
- wherein the light emitting device comprises:
- a device substrate having a first surface and a second surface;
- a light emitting stacked structure disposed on the second surface;
- and
- a first blocking pattern of the blocking pattern disposed on the first surface.
