  • Publication number: 20160178942
    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.
