Document Type and Number:
Japanese Patent JP6795260
Kind Code:
B2
Abstract:
An electrically tunable optical phase modulation element includes a first substrate, a second substrate, a liquid crystal layer, a transparent layer, a first compensation layer. The second substrate is opposite to the first substrate. The liquid crystal layer is between the first substrate and the second substrate. The transparent layer is between the first substrate and the liquid crystal layer. The transparent layer has a first portion and a second portion. The first compensation layer is in between the first portion and the second portion of the transparent layer. The first compensation layer has a flat surface adjacent the liquid crystal layer.
