Problems solved by technology

Liquid crystal molecules that are not controlled by fringing fields in the electrical domains may not be able to form a predetermined angle with the polarization axis of the polarizer, and thus may cause the user to see gray or black dots
Therefore, the transmittance of the display device may be reduced

Abstract

The present invention discloses a display device. The display device comprises: a first substrate including pixel electrodes arranged in first and second directions, each pixel electrode including a unit pixel electrode, a second substrate including a common electrode on which an opening pattern is formed, and a liquid crystal layer disposed between the first substrate and the second substrate. The unit pixel electrode includes a central electrode portion including diagonal sides, connection sides, a cross slit extending in the first and second directions, and central branch slits extending from the cross slit, and a branch electrode portion including branch electrodes protruding from each of the diagonal sides, in which the connection sides includes first and second connection sides extending in the first and second directions, and the central electrode portion has first outer areas adjacent to the first connection sides and on which first control slits extending in the first direction are respectively formed.

Description

[0001] Cross References to Related Applications [0002] This application claims priority and benefit from Korean Patent Application No. 10-2017-0142818 filed on October 30, 2017, which is hereby incorporated by reference for all purposes as if fully set forth herein. technical field [0003] Exemplary embodiments of the present invention generally relate to a display device having improved transmittance and side visibility. Background technique [0004] A liquid crystal display device may include a liquid crystal display panel including two substrates facing each other and a liquid crystal layer disposed between the substrates. A liquid crystal display device may form an electric field in a liquid crystal layer by applying a voltage to electrodes for generating an electric field. The electric field may determine alignment directions of liquid crystal molecules of the liquid crystal layer and control polarization of incident light to display images. [0005] A liquid cryst...
