Abstract:
In order to provide a reflection type liquid crystal display apparatus where, even when the pixel size is small, the crosstalk between a signal line and an end of a capacitor can be decreased, thus resulting in a good output image, by forming a signal line 2 for transmitting an image signal to each pixel with a second metal layer, by placing a shield line 12 between a capacitor electrode 10 constituting a capacitor and the signal line 2 with a first metal layer, and by giving a fixed potential, shielding is provided to prevent occurrence of cross-talk. The capacitor is configured with a common electrode 11 and a capacitor electrode 10, having a diffusion layer formed on a semiconductor substrate. By placing the capacitor electrode having a diffusion layer formed on the semiconductor substrate and the common electrode having a fixed potential below the signal line, shielding is provided to prevent occurrence of cross-talk.
