Abstract:
1. An electro-optical device that holds a liquid crystal layer between a first substrate and a second substrate, the electro-optical device comprising: a transistor; a first interlayer isolation film which covers the transistor; a first electrode which is electrically connected to a source or drain region via a first through hole of the first interlayer isolation film; a second interlayer isolation film which covers the first electrode; a reflection film which is formed at one of a plurality of pixels, the reflection film being disposed on the second interlayer isolation film, the reflection film being electrically connected to the first electrode via a plug disposed in a second through hole of the second interlayer isolation film; a dielectric multi-layer film which is formed on the upper layer side of the reflection film; a planarizing isolation film which is formed on the upper layer side of the dielectric multi-layer film, and buries a step of a reflection film formation area, the reflection film formation area having the reflection film and a boundary area, the boundary area being an area between adjacent reflection films; a first substrate side alignment film which is formed on the upper layer side of the planarizing isolation film, a second substrate side underlying film which is formed on the surface facing the first substrate in the second substrate; and a second substrate side alignment film which is formed on the surface of the second substrate side underlying film, wherein the reflection film, the dielectric multi-layer film, the planarizing isolation film, and the first substrate side alignment film are formed on the first substrate and are facing the second substrate, wherein an area of the reflection film includes an area of a semiconductor layer of the transistor in plan view, wherein the second substrate side underlying film and the planarizing isolation film are each formed of the same material.
