Abstract

A reflective layer 212 having an aperture 212 a for each pixel is formed on a first substrate 211, and a colored layer 214 for constituting a color filter is formed thereon. A surface protection layer 215 is formed on the colored layer 214, and a transparent electrode 216 is formed further thereon. The colored layer 214 is constituted so as to cover the aperture 212 a in a two-dimensional direction, but overlaps only a part of a reflection surface in the pixel in a two-dimensional direction.

Claims (8)

1. An electro-optical device comprising:

an electro-optical substance disposed between a pair of substrates;

a first pixel including a first reflective display region and a first transmissive display region, the first transmissive display region being located in a portion of the first pixel where the first reflective display region is not located;

a second pixel including a second reflective display region and a second transmissive display region, the second transmissive display region being located in a portion of the second pixel where the second reflective display region is not located;

a first reflective layer disposed in th first reflective display region of the first pixel;

a second reflective layer disposed in the second reflective display region of the second pixel;

a first colored layer disposed between one of the pair of substrates and the electro-optical substance layer, the first colored layer being in an overlapping condition with both the first light transmitting region and the first reflective display region within the first pixel in plan view, the first colored layer being in a non-overlapping condition with a portion of the first light reflecting region within the first pixel in plan view; and

a second colored layer disposed between one of the pair of substrates and the electro-optical substance layer, the second colored layer being in an overlapping condition with the entirety of the second pixel in plan view.
