ABSTRACT:
An active-matrix substrate includes: two kinds of lines arranged in a matrix on an insulating plate; switching elements each provided in the vicinity of an intersection of the two kinds of lines; an insulating film for flattening, covering an entire surface of the insulating plate so as to flatten the uneven surface of the insulating plate due to the presence of the lines and the switching elements; and pixel electrodes provided in a matrix on the insulating film for flattening. A concave portion for preventing a short-circuit from occurring between the pixel electrodes during a production process is formed in a region of the insulating film for flattening which corresponds to a gap between pixel electrodes which are adjacent to each other. Also, a method for fabricating the active-matrix substrate includes the step of forming a concave portion for preventing a short-circuit from occurring between the pixel electrodes in an exposed portion of the insulating film for flattening at a gap between the pixel electrodes adjacent to each other, forming the concave portion by an ashing treatment after forming the pixel electrodes in a matrix.
