Abstract
A method of varying a transmittance of a transparent conductive film includes forming the transparent conductive film on a substrate and injecting a high energy source into the transparent conductive film to vary the transmittance of the transparent conductive film.
Claims6
A method of manufacturing a flat panel display device, the method comprising:
- providing an insulating substrate having first and second regions;
- forming a pixel electrode and a black matrix on the first and second regions, respectively, using a half-tone mask;
- forming an insulating layer over the entire surface of the insulating substrate;
- forming a thin film transistor being electrically connected to the pixel electrode on a region corresponding to the black matrix;
- forming a planarization layer over the entire surface of the insulating substrate;
- and
- forming an opening portion to expose a portion of the pixel electrode.
