Patent ID: 7916247

Claim:
An electro-optic device comprising: a substrate; a pixel area on the substrate; a frame light-shielding film that defines the periphery of the pixel area, the frame light-shielding film having an opening outside of the pixel area, the frame light-shielding film including: a first frame-light shielding film layer; and a second frame-light shielding film layer formed on the first layer, the second frame-light shielding film layer being formed of a material having a reflection ratio lower than that of a material which constitutes the first frame-light shielding film layer; an alignment mark located in the opening of the frame light-shielding film, the alignment mark being formed in a layer together with the first frame-light shielding film layer without being formed in a layer where the second frame-light shielding film layer is formed; and an opening light-shielding film disposed between the alignment mark and the substrate, the opening light-shielding film being formed of a material having a reflection ratio lower than that of a material which constitutes the alignment mark.
