LIQUID CRYSTAL DISPLAY DEVICE

摘要

A liquid crystal display device (100) according to an embodiment of the present invention operates in a lateral electric field mode, and includes: first and second substrates (50, 60) disposed with a liquid crystal layer (70) interposed therebetween; a first electrode (16) and a second electrode (18) on the first substrate; and a first alignment film (28). The first alignment film includes a first alignment region (A1) in which liquid crystal molecules are to be aligned in a first alignment azimuth and a second alignment region (A2) in which liquid crystal molecules are to be aligned in a substantially orthogonal second alignment azimuth. When a voltage is applied between the first electrode and the second electrode, liquid crystal molecules in the first alignment region and liquid crystal molecules in the second alignment region rotate in an identical direction.

1. A liquid crystal display device of a lateral electric field mode, comprising: a liquid crystal layer; first and second substrates opposing each other with the liquid crystal layer interposed therebetween; first and second polarizers disposed respectively on the first and second substrates; a first electrode and a second electrode disposed on the liquid crystal layer side of the first substrate; and a first alignment film provided on the liquid crystal layer side of the first substrate so as to be in contact with the liquid crystal layer, the first alignment film regulating an alignment direction of liquid crystal molecules in the absence of an applied voltage, wherein,
the first alignment film has a first alignment region in which the liquid crystal molecules are to be aligned in a first alignment azimuth and a second alignment region in which the liquid crystal molecules are to be aligned in a second alignment azimuth substantially orthogonal to the first alignment azimuth, the second alignment region being adjacent to the first alignment region; and when a voltage is applied between the first electrode and the second electrode, liquid crystal molecules in a first domain corresponding to the first alignment region and liquid crystal molecules in a second domain corresponding to the second alignment region rotate in an identical direction.
