Abstract

A display device includes a seat holding the spacer. The seat is formed in a superposition region where at least the gate line, the semiconductor layer, the data line, and the organic insulator are superposed on one another in a laminated direction, the superposition region being a region facing the spacer. A whole outer periphery of the seat and the superposition region are superposed on each other in the laminated direction.

First claim

What is claimed is:

1 . A display device comprising:
a first substrate; a second substrate facing the first substrate; and a spacer disposed between the first substrate and the second substrate, wherein the first substrate includes:
a seat holding the spacer;
a plurality of gate lines extending in a row direction;
a first insulator covering the plurality of gate lines;
a semiconductor layer formed on the first insulator;
a plurality of data lines formed on the semiconductor layer to extend in a column direction;
a second insulator covering the plurality of data lines; and
an organic insulator formed on the second insulator,
wherein the seat is a region facing the spacer, the seat is formed in a superposition region where at least the gate line, the semiconductor layer, the data line, and the organic insulator are superposed on one another in a laminated direction, and a whole outer periphery of the seat and the superposition region are superposed on each other in the laminated direction.

2 . The display device according to claim 1 , further comprising: a plurality of pixel electrodes; a common electrode facing the plurality of pixel electrodes; and a common wiring that is electrically connected to the common electrode,
wherein the common electrode is formed on the organic insulator, the common wiring is formed on the common electrode, the common wiring includes a first common wiring extending in the row direction and a second common wiring extending in the column direction from the first common wiring, and the seat is the second common wiring formed in the superposition region.

3 . The display device according to claim 1 , further comprising: a plurality of pixel electrodes; a common electrode facing the plurality of pixel electrodes; and a common wiring that is electrically connected to the common electrode,
wherein the common electrode is formed on the organic insulator, the common wiring is formed on the common electrode, and the seat is a metallic layer that is formed in the superposition region, the metallic layer being formed in a layer identical to the common wiring and being separated from the common wiring.

4 . The display device according to claim 2 , wherein the first substrate further includes a third insulator,
the third insulator is formed so as to cover the common electrode and the common wiring, and the plurality of pixel electrodes are formed on the third insulator.

5 . The display device according to claim 1 , wherein the gate line, the semiconductor layer, and the data line protrude from the seat in a plan view.

6 . The display device according to claim 1 , wherein the gate line includes a protrusion that extends in the column direction in a region where the gate line overlaps the seat in a plan view.

7 . The display device according to claim 1 , wherein the data line includes a protrusion that extends in the row direction in a region where the data line overlaps the seat in a plan view.
