We have successfully achieved a very high contrast ratio of over 700:1 without attaching optical compensation films. This good contrast ratio is much higher than that for commercially available projection displays whose typical contrast ratios are about 400:1. A novel light‐shielding structure has been employed in order to realize the excellent performance that has been brought by suppressing low photo leakage current in the TFTs for the LCLVs.
