Abstract
A liquid crystal display panel which is viewable from a greater range of oblique viewing angles without apparent loss of contrast or color intensity includes a thin film transistor substrate, a color filter substrate, a liquid crystal layer between the color filter substrate and the thin film transistor substrate. The color filter substrate includes a glass substrate, a black matrix, and a color filter layer on the glass substrate. A surface of the glass substrate defines a plurality of grooves having different depths. Both the black matrix and the color filter layer are in the grooves. A thickness of the liquid crystal layer changes with depths of the plurality of grooves. A display device and a method for making the liquid crystal display panel are also provided.
