ABSTRACT:
A LCD panel having the large cell gap tolerance includes: an LC (Liquid Crystal) having properties changed by input voltage and changing a transmittance rate change of light incident from the outside; electrodes for applying voltage to the LC; base plates on which the electrodes are formed, each base plate having an LC layer located at prescribed intervals to inject the LC between the electrodes; a split pattern or a floating electrode formed inside each electrode, changing voltage applied to the LC and compensating a cell gap change; and a micro-lens attached on one side of one of the base plates and gathering lights, which are incident from the outside, on a central symmetric line of the slit pattern or the floating electrode. The LCD panel of large cell gap tolerance and the LCD projector using it include LCD panels having large LCD cell gap tolerance.
