Abstract
An active matrix substrate includes a thin film transistor including an oxide semiconductor layer, an interlayer insulating layer covering the thin film transistor, a pixel electrode provided above the interlayer insulating layer and electrically connected to the thin film transistor, a common electrode provided between the pixel electrode and the interlayer insulating layer, a first dielectric layer provided between the common electrode and the pixel electrode, and an alignment film covering the pixel electrode. The first dielectric layer includes a plurality of openings each of which exposes a part of the common electrode and includes the alignment film positioned therein.
