A liquid crystal display consistent with the present invention comprises an insulating substrate having a signal line and a scan line. The scan line forms a crossing pattern with the signal line. A switching device is connected to the signal line and the scan line. An interlayer insulating film is formed on top of the signal line, the scan line, and the switching device. A pixel electrode is formed on the interlayer insulating film and connected to the switching device. A trench is formed in a part of the interlayer insulating film where the pixel electrode is not formed. Finally, a black matrix is formed in a predetermined part of the trench.
