ABSTRACT:
There is provided a liquid crystal device that displays an image through a liquid crystal. The liquid crystal device includes: a plurality of pixels that constitutes the image; a light-shielding film disposed between the plurality of pixels; an opening provided at the light-shielding film; an open surface including the opening; and a plurality of condensers provided for the plurality of pixels, the condensers collecting light rays incident on the liquid crystal into the center of the respective pixels. A ratio C/P satisfies the relation 1<C/P<2.5 where P is the diagonal length of the pixel, C is the distance between A and B, where A is the intersection point between the optical axis of the light incident on the center of the pixel and the open surface, and B is the farthest point of the condenser on the optical axis from the intersection point A.
