Claim 18:
19. An electronic apparatus, comprising:
a liquid crystal display device, wherein the liquid crystal display device comprises:
a liquid crystal layer;
a drive substrate;
a plurality of pixel electrodes that is reflective and on the drive substrate;
a counter substrate opposite to the drive substrate with the plurality of pixel electrodes and the liquid crystal layer therebetween;
a first layer between the counter substrate and the liquid crystal layer, wherein the first layer includes a material having a first refractive index; and
a second layer in at least a portion of a region, in the first layer, corresponding to a location between the plurality of pixel electrodes, wherein

the second layer includes a material having a second refractive index lower than the first refractive index, and has a rectangular cross-sectional shape in a thickness direction, and
the second layer guides entering light to the plurality of pixel electrodes by a diffraction action.
