Placement of a first light shielding film at least below the channel region of a TFT which drives a pixel, and of a second light shielding film above the same prevents impingement of light coming from above or from below on that channel region. Further, a second light shielding film is formed to cover the channel region and the first light shielding film, thereby to prevent the surface of the first light shielding film from direct exposure to light.
