Abstract
A liquid crystal display device capable of preventing a semiconductor element from malfunctioning due to the light which enters the semiconductor element from the display side opposed to a light source side. The liquid crystal display device comprises a first substrate ( ), a second substrate and a liquid crystal sandwiched between the first substrate and the second substrate. The liquid crystal display device further comprises semiconductor elements (FG) formed over the first substrate and arranged in a matrix, and a light shielding film (BS) formed over the first substrate for blocking the light which would enter the semiconductor elements from the display face of the liquid crystal display device if not blocked.
