Abstract

A display device includes a display area (DA) and a non-display area (NDA), a first alignment layer (ALN1) disposed on a first substrate (SUB1), a second alignment layer (ALN2) disposed on a second substrate (SUB2), and a liquid crystal layer (LC) disposed between the first alignment layer and the second alignment layer. A groove (GRV) is disposed in the non-display area of the second substrate to correspond to at least a portion of an end portion of the second alignment layer.

Description

[0001] This patent application claims priority and all rights and interests arising from Korean Patent Application No. 10-2013-0031091 filed with the Korean Intellectual Property Office on March 22, 2013, the entire contents of which are hereby incorporated by reference here. technical field [0002] Embodiments of the present disclosure relate to a display device. More particularly, embodiments of the present disclosure relate to display devices with improved display quality. Background technique [0003] Generally, a liquid crystal display includes two transparent substrates and a liquid crystal layer disposed between the two substrates. The liquid crystal display drives liquid crystal molecules of a liquid crystal layer to control transmittance of light passing through each pixel to display desired images. [0004] A liquid crystal display includes an alignment layer to initially align liquid crystal molecules of a liquid crystal layer. An alignment layer is provided o...
