Apparatus and method for manufacturing a photopolymer thin film for liquid crystal molecular alignment

摘要

Azobenzene or the like is oriented on a sample surface in a predetermined direction by an electric field is converted into a cis-type or trans-type by a polarized ultraviolet ray or a visible ray, and at the same time, Discloses an apparatus and a method for producing an advertising molecule thin film for arranging liquid crystal molecules that coincide with the direction of polarization.;An apparatus for producing a thin film of advertising molecules for liquid crystal molecules according to the present invention comprises a vacuum chamber divided into an upper vacuum chamber 1 and a lower vacuum chamber 9 by a shutter 8; A sample holder (2) for applying an anode voltage provided in the upper vacuum chamber; A sample (3) fixed to the sample holder (2); An electrode (7) for applying a negative voltage; A light source 5 for generating an ultraviolet ray or a visible ray on one side of the outer surface of the upper vacuum chamber 1; A polarizer (4) for polarizing the ultraviolet or visible light provided in front of the light source (5); And a molybdenum-boat (10) in which a deposition material having a polarization and light-generating property provided in a lower vacuum chamber (9) is to be placed. According to the present invention, which comprises a light source for generating ultraviolet light or visible light and a polarizer for polarizing the light source, the present invention provides a deposition material having a property of polarization and light which is deposited in a predetermined direction with respect to a sample surface by an electric field Is transformed into a cis-type or trans-type, and is aligned on the substrate in a direction coinciding with the polarization direction of the ultraviolet or visible light.
