发明名称 Light shielding structure of a substrate for a liquid crystal device, liquid crystal device and projection type display device
摘要 Placement of a first light shielding film (7) at least below the channel region (1c) of a TFT which drives a pixel, and of a second light shielding film (3) above the same prevents impingement of light coming from above or from below on that channel region (1c). Further, a second light shielding film (3) is formed to cover the channel region (1c) and the first light shielding film (7), thereby to prevent the surface of the first light shielding film (7) from direct exposure to light.
