METHOD FOR MANUFACTURING SUBSTRATE FOR ELECTRO-OPTICAL DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a method for manufacturing a substrate for an electro-optical device by which the number of steps in the production process of a substrate for an electro-optical device can be reduced to improve production efficiency, an electro-optical device can be made thin and the viewing angle of the light transmitting a pixel region can be widened.

SOLUTION: The method includes steps of: forming a plurality of minute recessed portions on the surface of a first substrate 3a by a mechanical means; and etching the surface of the first substrate 3a to reduce the thickness of the first substrate 3a and isotropically erode the minute recessed portions to form microlenses L.
