Abstract

A LCD panel is disclosed that provides improved performance of the frame area that surrounds the panel's display area. The frame area includes a transparent substrate, and color filters provided side-by-side on the transparent substrate, each of the color filters filtering one of at least two colors. The LCD panel is further constituted by a first electrode that counters the color filters, a second electrode that counters the first electrode, and liquid crystal that is inserted between the electrodes. Display spots are suppressed and the frame can appear in a desired color when the panel is in operation.
