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.
