Abstract

A display apparatus includes a light source, a display unit in a plate shape including a display area on which light emitted by the light source is focused, a heat dissipation portion in a plate shape arranged on one side or another side in a plate thickness direction of the display unit, a housing containing the display unit and the heat dissipation portion, a first fixing portion provided on the housing to sandwich and fix the display unit and the heat dissipation portion in a plane extension direction intersecting the plate thickness direction, and a second fixing portion that limits displacement of the display unit and the heat dissipation portion by collectively pressing the display unit and the heat dissipation portion in the plate thickness direction.

First claim

What is claimed is:

1. A display apparatus comprising:
a light source;
a display unit in a plate shape including a display area on which light emitted by the light source is focused;
a heat dissipation portion in a plate shape arranged on one side or another side in a plate thickness direction of the display unit;
a housing containing the display unit and the heat dissipation portion;
a first fixing portion provided on the housing to come into contact with the display unit and sandwich and fix the display unit and the heat dissipation portion in a plane extension direction intersecting the plate thickness direction; and
a second fixing portion that limits displacement of the display unit and the heat dissipation portion by pressing the display unit and the heat dissipation portion together in the plate thickness direction.

2. The display apparatus according to claim 1 , wherein the housing is provided with a third fixing portion at a position of sandwiching the display unit and the heat dissipation portion in a direction that is different from a direction in which the first fixing portion sandwiches the display unit and the heat dissipation portion within the plane extension direction, and
the display unit and the heat dissipation portion are fixed to the third fixing portion by press fitting.

3. The display apparatus according to claim 1 , wherein a diffusion plate with unevenness is arranged between the display unit and the heat dissipation portion to form an air layer.

4. The display apparatus according to claim 1 , wherein the heat dissipation portion is a transparent member or a transparent member with heat dissipation property.

5. The display apparatus according to claim 1 , wherein the first fixing portion is arranged on a peripheral edge of the display unit, and
the first fixing portion is constituted by a pair of leaf springs opposing each other.

6. The display apparatus according to claim 1 , wherein the second fixing portion includes a buffer member that extends along a peripheral edge of the display area.

7. The display apparatus according to claim 6 , wherein the second fixing portion includes a cover member that holds the buffer member, covers a peripheral edge of the display unit and a peripheral edge of the heat dissipation portion, and fits into the housing,
the housing includes an opening portion that is open toward one side in an optical axis direction of light emitted by the light source,
the display unit and the heat dissipation portion are provided in proximity to the opening portion,
the first fixing portion is provided on the peripheral edge of the display unit, and
with the cover member being fitted in the housing, the buffer member is in contact with one of the display unit and the heat dissipation portion.
