Abstract
A substrate for a display device includes a scan line, a signal line, a switching element provided on an insulating substrate, an interlayer insulation film, and a pixel electrode. The switching element is provided at an intersection of the scan line and the signal line. The switching element includes a gate electrode connected to the scan line, a source electrode connected to the signal line, and a drain electrode connected to the pixel electrode. The interlayer insulation film includes a contact hole for connecting the drain electrode of the switching element to the pixel electrode. A protective layer formed of an insulating material is provided above the scan line and/or the signal line. A portion of an underlying film under the protective layer contacts a portion of an overlying film over the protective layer.
