Abstract

A liquid crystal display device is provided with a thin film transistor which includes a gate electrode film that is provided in a first electrode layer located over a first insulating layer, a semiconductor film that is disposed over the gate electrode film via a second insulating layer, a drain electrode and a source electrode that are provided in a second electrode layer located over the semiconductor film and are in contact with an upper surface of the semiconductor film, and a light blocking film that is disposed under the first insulating layer. At least a part thereof overlaps the semiconductor film and the gate electrode film in a plan view. One of the drain electrode and the source electrode is connected to a gate line, and the light blocking film is electrically connected to the source electrode.

First claim

What is claimed is:

1. A liquid crystal display device comprising:
a pixel;
a pixel transistor;
an image signal line that supplies an image signal to the pixel;
a scanning signal line that supplies a control signal to the pixel; and
an output transistor that outputs the control signal to the scanning signal line,
wherein the output transistor includes
a gate electrode film that is provided in a first electrode layer located over a first insulating layer;
a semiconduct…
