Abstract: Disclosed is a liquid crystal display apparatus in which a low-resistance alignment film and a low-resistance liquid crystal layer are provided only in red (R) and green (G) pixel areas so as to prevent bright pixel defects caused by occurrence of data coupling (DC). The liquid crystal display apparatus includes gate lines and data lines arranged on a first substrate so as to define red (R), green (G) and blue (B) pixel areas, thin film transistors provided at intersections between the gate lines and the data lines, a first alignment film provided on the first substrate, a second substrate arranged with a uniform gap with the first substrate, red, green and blue color filter layers provided on the second substrate, and a second alignment film provided on the second substrate, wherein the first alignment film provided on the red and green color filter layers is a low-resistance alignment film.

Abstract: A display device in one embodiment includes a display panel configured to display an image in first and second display areas, a plurality of first gate lines corresponding to the first display area, and a plurality of second gate lines separated from the first gate lines and corresponding to the second display area. Accordingly, the distance between the first gate lines of the first display area and the second gate lines of the second display area is maximized to prevent static electricity from occurring between the electrodes, thereby increasing product yield.
