ACTIVE MATRIX SUBSTRATE AND DISPLAY DEVICE

摘要

An active matrix substrate includes: a first inorganic insulating film (first insulating layer) provided on a gate insulating film (insulating film); an organic insulating film (second insulating layer) provided on the first inorganic insulating film and having a thermal expansion coefficient different from that of the first inorganic insulating film; and a second inorganic insulating film (third insulating layer) provided in such a manner as to cover the organic insulating film and partially contacting the first inorganic insulating film. A notch is provided above the gate insulating film and in a portion of the second inorganic insulating film where the organic insulating film is not present.

1. An active matrix substrate, comprising:
a base; a gate bus line provided on the base; and a data bus line provided in a layer different from that of the gate bus line with an insulating film interposed therebetween, the active matrix substrate further comprising: a first insulating layer provided on the insulating film; a second insulating layer provided on the first insulating layer and having a thermal expansion coefficient different from that of the first insulating layer; and a third insulating layer provided in such a manner as to cover the second insulating layer and partially contacting the first insulating layer, wherein at least part of a notch is provided above the insulating film and in a portion of the third insulating layer where the second insulating layer is not present.
