Patent ID: 7154460

Claim:
A substrate having a pixel electrode, comprising: a substrate; a plurality of pixel units, each pixel unit including a pixel electrode useable as a reflective electrode and a switching element electrically connected to the pixel electrode, the pixel units being arranged in a matrix pattern on the substrate, the switching element having a terminal electrode forming a conductive layer, a contact hole provided between the pixel electrode and the conductive layer that electrically connects the pixel electrode and the terminal electrode; a light-shielding layer having an opening surrounding a portion in which the contact hole is formed and having no opening in regions between adjacent pixel electrodes, the light-shielding layer being formed between the pixel electrode and the conductive layer; and an underlying insulating layer being formed below the pixel electrodes, and in regions between adjacent pixel electrodes of the plurality of pixel units, a groove having no flat surface on bottom and having a substantially V-shaped surface relative to an upper surface of the underlying insulating layer being formed in regions between adjacent pixel electrodes on a surface of the underlying insulating layer, the V-shaped surface for reflecting obliquely the light vertically incident which enters a space between the pixel electrodes.
