Abstract: In a method of forming an alignment layer, a first substrate, a second substrate opposite to the first substrate and a liquid crystal layer including a reactive mesogen are formed on a stage on which a groove is formed. The liquid crystal layer is disposed between the first and second substrates. An alignment layer is formed by exposing the liquid crystal layer to harden the reactive mesogen. Although the first and second substrates have a curved shape, the pretilt angles of the first and second alignment layers are matched such that a transmittance of the display panel increases and a response time decreases.

Abstract translation: 在形成取向层的方法中，在形成有凹槽的台上形成第一基板，与第一基板相对的第二基板和包括反应性液晶元的液晶层。 液晶层设置在第一和第二基板之间。 通过使液晶层暴露以硬化反应性液晶元来形成取向层。 虽然第一基板和第二基板具有弯曲形状，但是第一和第二对准层的预倾角匹配，使得显示面板的透射率增加并且响应时间减小。
