Abstract

In one embodiment, an array substrate for a flat display device includes a gate line extending in a first direction, a source line extending a in second direction orthogonally crossing the first direction. A switching element includes a semiconductor layer, a gate electrode electrically connected with the gate line, a source electrode electrically connected with the gate line in contact with the semiconductor layer and a drain electrode in contact with the semiconductor layer. An insulating film covers the source line and the switching element, and includes a contact hole exposing the drain electrode. A pixel electrode is formed on the insulating film. An insulating filling component is filled in the contact hole of the insulating film so as to be interposed between the drain electrode and the pixel electrode in a pixel in which the source line is short-circuited with the drain electrode.

Claims (24)

1. An array substrate for a flat display device having a plurality of pixels, comprising:

a gate line extending in a first direction;

a source line extending in a second direction orthogonally crossing the first direction;

a switching element including a semiconductor layer, a gate electrode electrically connected with the gate line, a source electrode electrically connected with the gate line in contact with the semiconductor layer and a drain electrode in contact with the semiconductor layer;

an insulating film covering the source line and the switching element, and having a contact hole exposing the drain electrode; and

a pixel electrode formed on the insulating film; wherein

an insulating filling component is filled in the contact hole of the insulating film so as to be interposed between the drain electrode and the pixel electrode in a pixel in which the source line is short-circuited with the drain electrode,

the insulating film includes a first interlayer insulating film arranged on the switching element and a second interlayer insulating film arranged above the first interlayer insulating film,

a common electrode is arranged between the first interlayer insulating film and the second interlayer insulating film in common to the plurality of pixels, and

a slit is formed in the pixel electrode of each pixel formed on the second interlayer insulating film so as to face the common electrode.

2. The array substrate for a flat display device according to claim 1 , wherein the filling component is formed of resin material.

3. The array substrate for a flat display device according to claim 1 , wherein the flat display device is formed so as to be driven in an FFS mode or an IPS mode.

4. An array substrate for a flat display device having a plurality of pixels, comprising:
