A 0.9” XGA liquid crystal light valve with low temperature Poly‐Si TFT has been developed by using a stacked capacitor structure. The stacked capacitor structure could reduce storage capacitor area because most of the capacitor area is located above the pixel components, such as bus‐lines and TFTs. Therefore, this structure could obtain the required storage capacitance without decreasing aperture ratio. A high aperture ratio of 65% and a high contrast ratio of over 500:1 have been achieved with the fabricated light valve.
