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 method for manufacturing a substrate for a display device comprises forming a first pattern within an active region of the substrate and at the same time forming a first overlay pattern at corner regions of the active region; and forming a second pattern within the active region of the substrate and at the same time forming a second overlay pattern at corner regions of the active region, wherein the first overlay pattern includes gradations arranged in a predetermined direction, and the second overlay pattern includes gradations arranged in the predetermined direction to face the gradations of the first overlay pattern.
