Abstract

An electro-optical apparatus includes an element substrate which includes a display region in which a plurality of light emitting elements are arranged in a matrix form, and a terminal region in which mounting terminals are arranged outside the display region; a sealing film which seals the plurality of light emitting elements; and a sealing substrate which is arranged on the element substrate via the sealing film, in which a distance between the sealing substrate and the mounting terminal is equal to or longer than a thickness dimension of the sealing substrate when seen from a surface normal direction of the element substrate.

Claims (18)

1. An electro-optical apparatus comprising:

an element substrate which includes a display region in which a plurality of light emitting elements are arranged in a matrix form, and a terminal region in which mounting terminals are arranged outside the display region;

a sealing film which seals the plurality of light emitting elements; and

a sealing substrate which is arranged on the element substrate via the sealing film,

wherein a distance between the sealing substrate and the mounting terminal is equal to or longer than a thickness dimension of the sealing substrate when seen from a surface normal direction of the element substrate.

2. The electro-optical apparatus according to claim 1 ,

wherein a distance between one side of the element substrate where the mounting terminals are arranged and the mounting terminal is equal to or longer than the half of the thickness dimension of the sealing substrate.

3. An electronic device comprising the electro-optical apparatus according to claim 2 .

4. The electro-optical apparatus according to claim 1 ,

wherein the light emitting element includes an anode, a cathode, and a light emitting layer which is interposed between the anode and the cathode,

the cathode covers a data line driving circuit provided in the terminal region, and

the sealing substrate covers a part of the cathode.

5. An electronic device comprising the electro-optical apparatus according to claim 4 .

6. An electronic device comprising the electro-optical apparatus according to claim 1 .

7. The electro-optical apparatus according to claim 1 , further comprising

a filler which is arranged between the sealing film and the sealing substrate, wherein the filler does not protrude from the sealing substrate toward the terminal region.

8. The electro-optical apparatus according to claim 1 , further comprising

a filler which is arranged between the sealing film and the sealing substrate, wherein a distance between the filler and the mounting terminal is equal to the distance between the sealing substrate and the mounting terminal.
