A grid polarization element and a photo alignment device

Title:

A grid polarization element and a photo alignment device

Document Type and Number:

Japanese Patent JP6015869

Kind Code:

B2

Abstract:

An absorptive grid polarization element includes a transparent substrate, and a stripe-like grid provided on the transparent substrate. Each of a plurality of linear parts which form the grid absorbs more s polarization light than p polarization light, and thus achieves a polarizing action. The transparent substrate is made of quartz glass. Each of the linear parts includes a second layer formed on the transparent substrate, and a first layer formed on the second layer. The first layers are formed from amorphous titanium oxide. The second layers are formed from amorphous silicon.
