Liquid crystal display device

摘要

A liquid crystal display device using a horizontal electric field mode, in which contrast ratio is improved, is provided. A first polarizing plate having a polarization axis along a first direction, a second polarizing plate having a polarization axis along a second direction orthogonal to the first direction, a plurality of first structure bodies provided over a first substrate, a plurality of second structure bodies provided over the first substrate, a first electrode layer covering top surfaces and side surfaces of the plurality of first structure bodies, and a second electrode layer covering top surfaces and side surfaces of the plurality of second structure bodies are provided. The side surfaces of the first structure bodies and the side surfaces of the second structure bodies are parallel to the first direction or the second direction. Thus, a liquid crystal display device in which contrast ratio is improved can be provided.
