Display, display system, image projection system, and movable object

1. A display comprising:

a liquid-crystal panel including a display screen;

a heat-transfer member which is light-transmissive and is on an opposite side of the liquid-crystal panel from the display screen; and

a light-diffusion member between the liquid-crystal panel and the heat-transfer member, wherein

the heat-transfer member and the light-diffusion member are plate-shaped;

the light-diffusion member is thinner than the heat-transfer member; and

the light-diffusion member has a thickness equal to or smaller than 300 μm.

2. The display according to claim 1 , wherein

the light-diffusion member has a transmittance equal to or larger than 70%.

3. The display according to claim 1 , wherein

the heat-transfer member is directly contacted to the light-diffusion member.

4. An image projection system comprising:

the display according to claim 1 ;

a backlight emitting light toward the heat-transfer member; and

a heat sink accommodating the heat-transfer member and the backlight, wherein

light emitted from the backlight diverges in a direction toward the heat-transfer member.

5. The image projection system according to claim 4 , wherein

the heat sink has a plurality of plate-shaped fins protruding from an outer surface of the heat sink in a direction intersecting a direction in which the light-diffusion member and the light-transmissive member are arranged.

6. An image projection system comprising:

the display according to claim 1 ;

a backlight emitting light toward the heat-transfer member;

a heat sink accommodating the heat-transfer member and the backlight, wherein

light emitted from the backlight converges in a direction toward the heat-transfer member.

7. A head-up display, comprising:

a display according to claim 1 ;

a backlight; and

a projection unit that forms a virtual image corresponding to an image displayed on the display screen of the display, in a target space.
