Display apparatus provided with movable substrate covers securing edges of a front cover and its corresponding reinforcing plate

1. A display apparatus comprising:

a rectangular thin plate form display device with a surface on one side in the thickness direction thereof as a display surface configured to display an image and with a surface on the other side as a back surface;

rigid substrates each connected to an edge of said display device through a flexible substrate, operative to drive said display device, and each being elongate along said edge of said display device;

a front cover covering said display surface of said display device;

a rectangular thin plate form reinforcing plate attached to said back surface of said display device; and

a rear cover covering said back surface of said display device and a back surface of said reinforcing plate;

wherein said front cover having a front surface part located on the front side of said display surface, and side surface parts bent respectively from four edges of said front surface part to the rear side, and

said rigid substrates are bent to the rear side respectively via the corresponding flexible substrates and are respectively overlapped with and attached to the four edges of the back surface of said reinforcing plate,

wherein substrate covers are provided for respectively covering said rigid substrates overlapped with the four edges of said back surface of said reinforcing plate,

said substrate covers each have a back surface part located on the rear side of said rigid substrate, and a side surface part bent from an end portion of said back surface part to the front side, and are movable in the directions for spacing away respectively from the edges of said reinforcing plate in the plane of said reinforcing plate, and

outside surfaces of front portions of said side surface parts of said substrate covers are set in contact with, and joined to, the inside surfaces of said side surface parts of said front cover.

2. The display apparatus as set forth in claim 1 ,

wherein said rear cover has a back surface part located on the rear side of said back surface of said display device and said reinforcing plate, and side surface parts bent respectively from four edges of said back surface part; and

the front ends of said side surface parts of said rear cover front respectively on the rear ends of said side surface parts of said front cover, and a back surface part of said rear cover is screwed to said reinforcing plate.

3. The display apparatus as set forth in claim 1 , wherein said substrate covers extend respectively over the whole lengths of the four edges of said reinforcing plate.

4. The display apparatus as set forth in claim 1 , wherein said side surface parts of said substrate covers are located respectively on lateral sides of said flexible substrates, and cover said flexible substrates respectively.

5. The display apparatus as set forth in claim 1 , wherein said back surface parts of said substrate covers are disposed to be spaced respectively from said rigid substrates, and said side surface parts of said substrate covers are disposed to be spaced respectively from said flexible substrates.

6. The display apparatus as set forth in claim 1 , wherein said substrate covers are formed by use of a metallic material or rigid synthetic resin which is rigid enough to protect said rigid substrates and to support said front cover.

7. The display apparatus as set forth in claim 1 , wherein said reinforcing plate is formed by use of a metallic material having excellent heat radiating property, and is attached to said back surface of said display device through a heat conducive sheet.

8. The display apparatus as set forth in claim 1 , wherein said display device is an organic EL display.

9. The display apparatus as set forth in claim 1 , wherein said front cover is formed by use of a synthetic resin material.
