Abstract:
A manufacturing method for a reflection type liquid crystal display having a reflection film for reflecting light having passed through a liquid crystal layer, the method comprising:forming a thin film transistor on a substrate; forming a photosensitive resin film on the thin film transistor; exposing the photosensitive resin film with a first unit exposure light amount via a first mask; exposing the photosensitive resin film with a second unit exposure light amount via a second mask; developing the photosensitive resin film subjected to two exposures thereby forming two types of concaves having different depths; and forming a film using a reflective material on the photosensitive resin developed to have two types of concaves, thereby forming the reflection film; wherein the photosensitive resin film constitutes an insulating film, the reflection film is a reflection electrode having a size corresponding to a pixel, and the reflection electrode is electrically connected to the thin film transistor, and wherein the first unit exposure light amount is larger than the second unit exposure light amount, the concave formed using the first mask constitutes a contact hole for electrically connecting the reflection electrode and the thin film transistor, and the concave formed using the second mask constitutes a concave formed on a surface of the reflection electrode.
