ABSTRACT:
The invention provides an electro-optical device provided including a light reflector having a light diffusion function in a preferable condition while an increase in manufacturing cost thereof is minimized, and also provides an electronic apparatus using the same. The present invention can include an active matrix type reflective or transflective electro-optical device wherein, on a surface of a light reflector of an array substrate, irregularity-forming thin-films can be formed by patterning thin-films composed of the same layers as those forming a underlying protection film, a gate insulation film, a scanning line, a first interlayer insulation film, a data line, and a second interlayer insulation film so as to have predetermined patterns. Since an irregular pattern is formed by steps and irregularity of the irregularity-forming thin-films mentioned above, incident light on an counter substrate can be reflected thereto while being diffused.
