Abstract
The present invention provides a translucent reflection type electro-optic device that can increase a display light amount in both a reflection mode and a transmission mode, an electronic instrument therewith, and a method of fabricating the translucent reflection type electro-optic device. In a TFT array substrate of a reflection type electro-optic device, on a bottom layer side of a light reflection film, a concavity and convexity formation layer that forms a concavity and convexity pattern can be formed with a first photosensitive resin having a refractive index, n , on a top layer of the concavity and convexity formation layer a top layer insulating film made of a second photosensitive resin having a refractive index, n (n >n ), is formed, and at a position that overlaps with convexities of the concavity and convexity pattern, a light transmission window is formed. Accordingly, an interface between the concavity and convexity formation layer and the top layer insulating film plays a function as a condenser lens that refracts a light incident from a back surface side toward the light transmission window.
