Patent ID: 8125580

Claim:
A liquid crystal display apparatus, comprising: a liquid crystal panel having a pixel region in which first and second electrodes apply an electric field to a liquid crystal layer to display an image, wherein, said liquid crystal panel includes a photo-sensor element having a light receiving face at which said photo-sensor element receives incident light through said liquid crystal layer in the pixel region to produce received light data, at least one of said first and second electrodes is formed in a region of the pixel region other than a light receiving face corresponding region of the pixel region which corresponds to the light receiving face of said photo-sensor element, at least one of said first and second electrodes includes the light receiving face corresponding region and is not formed in a first region greater than the light receiving face corresponding region but formed in any other region than the first region, and said liquid crystal panel includes a filter layer provided in the pixel region in such a manner as to transmit therethrough an amount of invisible rays greater than the amount of visible rays from within the light incident to the light receiving face of said photo-sensor element.
