Patent ID: 7084940

Claim:
An electro-optic device, comprising: a recess/projection forming layer having asperities formed in a dispersed condition; a multiplicity of pixels formed in a matrix pattern on a substrate for holding an electro-optic material; and a light reflecting film formed above said recess/projection forming layer being disposed in each of the multiplicity of pixels, and said recess/projection forming layer forming a recess/projection pattern to scatter light on a surface of said light reflecting film, the multiplicity of pixels being grouped into plural units each including a plurality of pixels, the recess/projection pattern being formed to provide a different pattern for each pixel at least in each of the units and the recess/projection pattern for the pixel at the same position in each unit differing among the units, an asperity forming pattern larger than one pixel being set as a reference pattern, and positions of the projections and the recesses constituting said asperities for each of the pixels being decided using a recess/projection pattern which is obtained by rotating the reference pattern about a predetermined position, said light reflecting film being electrically connected to a lower or upper conductive layer through a contact hole and being formed except for said contact hole, and the center of rotation of the reference pattern being set to a position overlapping with said contact hole.
