Fabrication of TFT‐LCD panels of high resolution and aperture ratio was demonstrated by using a low‐k dielectric film as a passivation layer for the first time. The low‐k dielectric films were successfully deposited and patterned using a conventional PECVD and plasma‐assisted etching techniques, causing no drastic modification to the standard TFT process. Thin film transistors having the a‐Si:C:O:H passivation showed a transfer characteristics similar to that of conventional TFT's. The high transmittance panel showed brightness approximately 30% higher than that of a standard panel without degrading other display characteristics, such as cross‐talk.
