Patent ID: 7245337

Claim:
A liquid crystal display, comprising: a device substrate on which interconnections, thin film transistors and storage capacitors are formed; an opposite substrate so arranged as to face said device substrate; a liquid crystal layer sandwiched between said device substrate and said opposite substrate; a color filter formed on said thin film transistors; a reflection electrode formed on said color filter and having an undulated shape; and openings provided in a non-effective area of said reflection electrode, wherein the undulated shape is formed by projection patterns having an insulating layer disposed thereon, wherein a parameter of the undulated shape controls distribution of the non-effective area, the parameter including at least one of: (i) a center distance between the projection patterns, (ii) a width of the projection patterns, (iii) a height of the projection patterns, (iv) a height at a point at which a height of the insulating layer is a minimum, and (v) a height difference between a point at which the height of the insulating layer is a maximum and the point at which the height of the insulating layer is the minimum, and wherein the parameter controls distribution of a tilt angle of the non-effective area.
