REFLECTION TYPE ELECTROOPTICAL DEVICE, PROJECTION TYPE DISPLAY DEVICE, AND METHOD OF MANUFACTURING REFLECTION TYPE ELECTROOPTICAL DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a reflection type electrooptical device securely preventing that incident light from a gap of a light reflecting layer reaches a pixel switching element, without using a complicated structure, and to provide a projection type display device with the reflection type electrooptical device and a manufacturing method of the reflection type electrooptical device.;SOLUTION: In the reflection type electrooptical device 100, as there is a gap area 9s between adjoining pixel electrodes 9a in an element substrate 10, a trench shape concave section 8e is formed along the gap area 9s in a surface of an interlayer insulating film 8, and high refractive index material 4e which is more refractive than the interlayer insulating film 8 is filled up in the trench shape concave section 8e. Thereby, similar refraction with a convex lens occurs in an interface between the high refractive index material 4e and the interlayer insulating film 8, in the trench shape concave section 8e.;COPYRIGHT: (C)2009,JPO&INPIT
