Patent ID: 8054426

Claim:
A liquid crystal display device comprising: first and second substrates; a plurality of gate and data lines on the first substrate to define a plurality of pixel regions; a thin film transistor in each pixel region of the first substrate; a pixel electrode in each pixel region of the first substrate and a common electrode on the second substrates to form an electric field between the first and second substrates; at least one first slit of a circular-stripe shape in the pixel electrode within the pixel regions of the first substrate, the pixel electrode covering the whole area of the inner portion of the first slit, the width of the first slit being smaller than the radius of the pixel electrode at the inner portion of the first slit from the center to the first slit; at least one second slit of circular shape of predetermined radius in the common electrode within the pixel regions of the second substrate, the second slit being formed in the region corresponding to the center of the circular-stripe shaped first slit, the area of a color filter layer of the second substrate within the second slit being totally exposed; and a liquid crystal layer between the first and second substrates, wherein the pixel electrode is disposed in the whole area of the pixel region except for the first slit area on the first substrate so that the second slit of the second substrate is facing to the pixel electrode of the first substrate and the common electrode is disposed in the whole area of the second substrate except for the second slit area.
