Abstract
A display device is a display device that includes a display panel from which display light showing an image exits and a light source that emits basal light for producing the display light. The display device includes: a first diffusion sheet that diffuses the basal light that is to enter the display panel; a second diffusion sheet that is disposed spaced apart from the first diffusion sheet, and diffuses the basal light that is to enter the first diffusion sheet; and an optical member that includes a plurality of optical elements each of which refracts the basal light that is to enter the second diffusion sheet.
Claims10
A display device that includes a display panel from which display light showing an image exits and a light source that emits basal light for producing the display light, the display device comprising:
- a first diffusion structure that diffuses the basal light that is to enter the display panel;
- a second diffusion structure that is disposed spaced apart from the first diffusion structure, and diffuses the basal light that is to enter the first diffusion structure;
- and
- an optical member that includes a plurality of optical elements each of which refracts the basal light that is to enter the second diffusion structure.
A head-up display that includes a display device including a display panel from which display light showing an image exits and a light source that emits basal light for producing the display light, the head-up display comprising:
- a first diffusion structure that diffuses the basal light that is to enter the display panel;
- a second diffusion structure that is disposed spaced apart from the first diffusion structure, and diffuses the basal light that is to enter the first diffusion structure;
- an optical member that includes a plurality of optical elements each of which refracts the basal light that is to enter the second diffusion structure;
- and
- a mirror that reflects the display light that exits from the display panel.
