A wiring delay is prevented or reduced by lowering a wiring resistance without making a wire wider. The present invention includes: a light blocking film (102); a light-transmitting film (106); and a first wiring layer (105A) which serves as part of a wire configured to electrically control an amount of transmitted light for each pixel, the first wiring layer (105A) being provided over the light blocking film (102), and the light-transmitting film (106) being provided over the first wiring layer (105A) so as to cover a side surface of the first wiring layer.
