Abstract:
1. An active matrix type electro-optical device, comprising: a plurality of pixels arranged in a matrix on a substrate holding an electro-optical material; and each pixel including a thin film transistor that switches pixels, an irregularity forming film on which a plurality of irregularities including protrusions or holes are dispersed, and a light-reflecting film formed on the irregularity forming film, the light-reflecting film having on its surface an irregular pattern that scatters light due to the irregularity forming film, and the light-reflecting film being formed in contact holes which are formed in an interlayer insulating film, each of the plurality of pixels having a contact hole formation-position, the plurality of pixels containing a first array of pixels and a second array of pixels, the first and second array of pixels having identical dimensions, a pattern of contact hole formation-position in the first array of pixels being different from a pattern of contact hole formation-position in the second array of pixels.
