1. A liquid crystal panel substrate comprising:
- a substrate;
a pixel region including at least a reflecting electrode and a first light shielding film, the first light shielding film interposed between the reflecting electrode and the substrate;
a switching element disposed outside the pixel region; and
a wire electrically connected to the switching element, the wire being formed in the same layer as the first light shielding film.

Abstract
In a liquid crystal substrate in which a matrix of reflecting electrodes is formed on a substrate, a transistor is formed corresponding to each reflective electrode and a voltage is applied to the reflective electrode through the transistor. A silicon oxide film having a thickness of 500 to 2,000 angstroms is used as the passivation film and the thickness is set to a value in response to the wavelength of the incident light to maintain a substantially constant reflectance.
