Abstract
A reflective-electrode-side substrate of a reflective-type liquid crystal panel substrate has a pixel region including a pixel electrode, reflecting part, a light shielding film, and a switching element. A periphery region in the periphery of the pixel region outside of the pixel region includes a driving circuit that includes at least one switching element, and a wiring layer that is electrically connected to the at least one switching element. The switching elements may consist of transistors. This configuration can reduce the amount of light leaking through spaces between pixel electrodes and prevent adverse effects on image quality.
