Abstract: A dual side display includes reflection and transmission pixels for displaying an image on both sides of the display. A reflection film provided in a reflection pixel region is extended up to a transmission storage capacitor formation region of a transmission pixel such that the aperture ratio of the reflection pixel is enhanced. An upper storage electrode connected to a transmission storage line is formed between the reflection film and a lower storage electrode of the transmission storage capacitor to prevent a coupling phenomenon between the reflection film and the lower storage electrode and a resulting signal distortion.

Abstract: Disclosed is a picture quality testing apparatus and method of a liquid crystal display which can measure at least any one of gray inversion and color shift. An apparatus for testing the picture quality of a liquid crystal display includes a liquid crystal display for displaying a test pattern, an image pickup device for photographing the test pattern of the liquid crystal display, a measurer for measuring the transmittance of the test pattern photographed by the image pickup device, and a rotating means for rotating at least one of the liquid crystal display and the image pickup device while the image pickup device photographs the test pattern.
