Abstract:
1. An active matrix substrate for use in a reflection type liquid crystal display apparatus comprising: a display region including a first display region in which a plurality of first pixels each provided with a reflection electrode and a switching element for displaying an image are arranged on a substrate, and a second display region in which a plurality of second pixels each provided with a reflection electrode for displaying only a black displaying are arranged on the substrate; a wiring layer arranged between the switching element and a layer forming the reflection electrode; a light shielding layer arranged between the wiring layer and the layer forming the reflection electrode; a first through hole arranged between the wiring layer and the light shielding layer in the first display region, for electrically connecting the reflection electrode of the first pixel to the switching element of the first pixel; and a second through hole arranged between the wiring layer and the light shielding layer in the second display region, and being isolated electrically from the switching element.
