    • 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.
    • 液晶面板包括具有限定像素区域的像素的第一基板和设置在第一基板上的像素区域中的像素电极和公共电极。 为各像素设置像素电极。 液晶面板还包括与第一基板相对的第二基板和设置在第二基板上的遮光膜。 遮光膜包括围绕像素区域的框架部分和至少设置在像素区域中的中间部分。 中间部分由具有比框架部分更高的电阻率的材料制成。 框架部分由具有比中间部分更高的遮光性的材料制成。
