Display device and head-up display device
According to one embodiment, a display device includes a backlight device including a plurality of light sources, a display panel disposed to oppose the backlight device and incline with respect to a direction perpendicular to an optical axis of the backlight device and a diffusion plate provided between the display panel and the backlight device.
1. A display device comprising:
a backlight device comprising a plurality of light sources;
a display panel disposed to oppose the backlight device and incline with respect to a direction perpendicular to an optical axis of the backlight device; and
a diffusion plate between the display panel and the backlight device,
wherein the diffusion plate is inclined by −10 to +10 degrees with respect to a direction perpendicular to the optical axis of the backlight device.
2. The device of claim 1 , wherein
the diffusion plate is provided adjacent to a backlight device side with respect to a middle position between the display panel and the backlight device on a central axis of the display panel.
3. The device of claim 1 , wherein
an inclination angle of the display panel is 1 to 30 degrees.
4. The device of claim 3 , wherein
the diffusion plate is provided perpendicular to the optical axis of the backlight device.
5. The device of claim 1 , wherein
the diffusion plate comprises a glossy surface, which opposes the display panel.
6. The device of claim 1 , wherein
the backlight device is configured to turn on the plurality of light sources individually and control a lighting portion according to a display image.
7. The device of claim 1 , further comprising a second diffusion plate provided between the diffusion plate and the display panel.
8. A display device comprising:
a backlight device comprising a plurality of light sources;
a display panel disposed to oppose the backlight device and incline with respect to a direction perpendicular to an optical axis of the backlight device, an inclination angle of the display panel being 1 to 30 degrees;
a diffusion plate between the display panel and the backlight device; and
a second diffusion plate provided between the diffusion plate and the display panel,
wherein the diffusion plate and the second diffusion plate are disposed with a gap therebetween, and
wherein the second diffusion plate is arranged at a predetermined angle with respect to the diffusion plate.
9. The device of claim 8 , wherein
the second diffusion plate is arranged parallel to the diffusion plate.
10. A head-up display device comprising:
a backlight device comprising:
a plurality of light sources;
a display panel disposed to oppose the backlight device and incline with respect to a direction perpendicular to an optical axis of the backlight device; and
a diffusion plate between the display panel and the backlight device; and
a projection surface on which a display image of the display panel is projected,
wherein the diffusion plate is inclined by −10 to +10 degrees with respect to a direction Perpendicular to the optical axis of the backlight device.
11. The head-up display device of claim 10 , wherein the diffusion plate is provided adjacent to a backlight device side with respect to a middle position between the display panel and the backlight device on a central axis of the display panel.
12. The head-up display device of claim 10 , wherein an inclination angle of the display panel is 1 to 30 degrees.
13. The head-up display device of claim 12 , wherein the diffusion plate is provided perpendicular to the optical axis of the backlight device.
14. The head-up display device of claim 10 , wherein a surface of the diffusion plate, which opposes the display panel is a glossy surface.
15. The head-up display device of claim 10 , wherein the backlight device is configured to turn on the plurality of light sources individually and control a lighting portion according to a display image.
