Abstract
The TFT substrate of this liquid crystal display device has: a first gate bus line and a second gate bus line; a first data bus line; a first TFT and second TFT that are respectively connected to the first and second gate bus line and are both connected to the first data bus line; and a first pixel electrode and second pixel electrode that are respectively connected to the first TFT and the second TFT through a contact hole. The first and second gate bus line traverse the first pixel electrode and the second pixel electrode, and a black matrix has a portion that integrally covers the first TFT and the contact hole, and a portion that integrally covers the second TFT and the contact hole.
Claims15
A liquid crystal display device, comprising:
- a thin film transistor substrate;
- an opposite substrate;
- a liquid crystal layer disposed between the thin film transistor substrate and the opposite substrate, the liquid crystal layer being formed of liquid crystal material having a negative dielectric anisotropy;
- and
- a black matrix disposed on an outside of the liquid crystal layer, the black matrix having light-shielding characteristics,
- wherein the thin film transistor substrate includes:
- a first gate bus line extending along a first direction, and a second gate bus line extending parallel and adjacent to the first gate bus line;
- a first data bus line extending along a second direction that intersects with the first direction;
- a first thin film transistor and a second thin film transistor that are respectively connected to the first gate bus line and the second gate bus line and that are both connected to the first data bus line, the first thin film transistor and the second thin film transistor being disposed along the first direction side-by-side;
- and
- a first pixel electrode and a second pixel electrode that are respectively connected to the first thin film transistor and the second thin film transistor through a first contact hole and a second contact hole, respectively, the first pixel electrode and the second pixel electrode being disposed along the first direction side-by-side,
- wherein, when seen from a direction normal to the thin film transistor substrate, the first gate bus line and the second gate bus line cross the first pixel electrode and the second pixel electrode and are disposed so as to overlap the first pixel electrode and the second pixel electrode, and
- wherein the black matrix has a first inter-pixel light-shielding portion that covers both the first thin film transistor and the first contact hole and a second inter-pixel light-shielding portion that covers both the second thin film transistor and the second contact hole.
