摘要:
A liquid crystal panel includes a first substrate having pixels defining a pixel region, and pixel electrodes and a common electrode disposed in the pixel region on the first substrate. The pixel electrodes are disposed for the respective pixels. The liquid crystal panel also includes a second substrate opposing the first substrate and a light-shielding film disposed on the second substrate. The light-shielding film includes a frame portion surrounding the pixel region and a middle portion disposed at least in the pixel region. The middle portion is made of a material having a higher specific resistance than the frame portion. The frame portion is made of a material having a higher light-shielding property than the middle portion.
