Abstract
A display device includes: a display panel that includes, in a front surface, a display area in which an image is displayed, and projects, from the display area, light that has entered from a back surface as display light showing the image; a thermal conductive sheet that is disposed contacting the display panel, and has an opening positionally corresponding with the display area; and a light transmissive material that sandwiches the thermal conductive sheet together with the display panel.
Claims12
A display device used for a head-up display, the display device comprising:
- a display panel that includes, in a front surface, a display area in which an image is displayed, and projects, from the display area, light that has entered from a back surface as display light showing the image;
- a thermal conductive sheet that is disposed directly contacting the display panel, and has an opening positionally corresponding with the display area;
- a light transmissive material that sandwiches the thermal conductive sheet together with the display panel;
- and
- a housing for accommodating the display panel, wherein
- a perimeter of the thermal conductive sheet is greater than a perimeter of the display panel, and
- in a view perpendicular to the display area of the display panel, a periphery of the thermal conductive sheet is located outward of a periphery of the light transmissive material, and contacts the housing.
