Abstract:
A method of making a liquid crystal display including an array of thin film transistors (TFTs), comprising:providing a substantially transparent first substrate; disposing a gate metal layer on said first substrate and patterning an array of TFT gate electrodes and gate address lines therefrom; disposing a semiconductor layer on said first substrate over said gate electrodes and patterning the semiconductor layer to form TFT areas; disposing and patterning drain and source electrodes on said substrate over the semiconductor layer; providing drain address lines for addressing the drain electrodes; disposing a substantially continuous organic insulating layer on said substrate over said address lines and said drain and source electrodes to a thickness of at least about 1.5 &mgr;m; and disposing and patterning an array of substantially transparent pixel electrodes on said substrate over said insulating layer so that the patterned pixel electrodes overlap at least one of said gate and drain lines in order to increase the display's pixel aperture ratio, wherein a parasitic capacitance corresponding to an overlap of one of the pixel electrodes to one of the gate and drain lines is no greater than 0.01 pF.
