Abstract

An electro-optic device includes an electro-optic panel and a light-shielding section. The light-shielding section formed on a side of a light exiting surface of the electro-optic panel and includes an inclined surface inclined toward a side opposite to the light exiting surface.

Claims (21)

1. An electro-optic device comprising:

an electro-optic panel which has a pixel area where a plurality of pixels are arranged;

an ocular lens that enlarges an image displayed by the electro-optic panel, the ocular lens having a diameter larger than a width of the pixel area; and

a light-shielding section formed on a side of a light exiting surface of the electro-optic panel along at least a part of the circumference of the pixel area, the light-shielding section being disposed between the electro-optic panel and the ocular lens, the light-shielding section including an inclined surface extending from a region outside the circumference of the pixel area obliquely toward the pixel area and away from the light exiting surface of the electro-optic panel such that a portion of light passing through the ocular lens toward the electro-optic panel is intercepted by the light-shielding portion.

2. The electro-optic device according to claim 1 ,

wherein the electro-optic panel has a light-shielding film formed in a frame shape in the circumference of the pixel area, and

wherein in the outer periphery of the light-shielding film outside the pixel area, the light-shielding section at least partially defines a window through which display light exits to correspond to the pixel area.

3. The electro-optic panel according to claim 1 , further comprising:

a mounting case which accommodates the electro-optic panel by surrounding the circumference of the electro-optic panel,

wherein the light-shielding section is formed as a part of the mounting case.

4. The electro-optic device according to claim 3 ,

wherein the mounting case includes a first holding member having an opening section surrounding the electro-optic panel and a second holding member mounted in the first holding member so as to cover the opening section, and

wherein the light-shielding section is formed as a part of the second holding member.

5. The electro-optic device according to claim 4 , further comprising:

an optical member which is accommodated in the mounting case and at least partially forms a predetermined optical system for light incident on and exiting from the electro-optic panel,

wherein the optical member is disposed such that a gap is formed between the optical member and the mounting case.

6. The electro-optic device according to claim 3 ,

wherein the mounting case includes a first member having a concave portion accommodating the electro-optic panel and a second member disposed between the electro-optical panel and the ocular lens, the second member having a reflexibility lower than the first member, and

wherein the light-shielding section is formed as a part of the second member.

7. The electro-optic device according to claim 1 , wherein the light-shielding section is inclined at an angle of 30° or less with respect to the light exiting surface.

8. An electronic apparatus comprising the electro-optic device according to claim 1 .
