Abstract

A display device is provided. The display device includes a first base substrate, a gate line on the first base substrate and extending in a first direction, a data line disposed on the first base substrate, insulated from the gate line, and extending in a second direction, which crosses the first direction, a switch on the first base substrate and electrically connected to the gate line and the data line, an insulating layer on the switch, a first electrode on the insulating layer, a light-shielding conductive layer directly contacting the first electrode and overlapping the switch, and a second electrode insulated from the first electrode and the light-shielding conductive layer, at least partially overlapping the first electrode, and electrically connected to the switch.

Claims (42)

1. A display device, comprising:

a first base substrate;

a gate line on the first base substrate and extending in a first direction;

a data line on the first base substrate, insulated from the gate line, and extending in a second direction, which crosses the first direction;

a switch on the first base substrate and electrically connected to the gate line and the data line;

an insulating layer on the switch;

a first electrode on the insulating layer;

a light-shielding conductive layer directly on the first electrode and overlapping the switch

an auxiliary light-shielding member extending in the second direction, the auxiliary light-shielding member directly on the first electrode and overlapping the data line; and

a second electrode insulated from the first electrode and the light-shielding conductive layer, at least partially overlapping the first electrode, and electrically connected to the switch,

wherein the auxiliary light-shielding member includes the same material as the light-shielding conductive layer.

2. The display device as claimed in claim 1 , further comprising:

a contact hole, which at least partially exposes the switch through the insulating layer;

a first opening, which overlaps the contact hole, through the first electrode;

a second opening, which overlaps the first opening, through the light-shielding conductive layer; and

a light-shielding member, which overlaps the contact hole, the first opening, and the second opening.

3. The display device as claimed in claim 2 , wherein the light-shielding member has an island-shaped planar shape and does not overlap the data line.

4. The display device as claimed in claim 2 , wherein:

a maximum width, in the first direction, of the second opening is less than or equal to a maximum width, in the first direction, of the light-shielding member, and

a maximum width, in the second direction, of the second opening is less than or equal to a maximum width, in the second direction, of the light-shielding member.

5. The display device as claimed in claim 1 , wherein the auxiliary light-shielding member is directly connected to the light-shielding conductive layer.

6. The display device as claimed in claim 2 , wherein an inner side of the first opening and an inner side of the second opening are disposed substantially on a same line.

7. The display device as claimed in claim 2 , wherein a distance between an inner side of the first opening and an inner side of the second opening is between 0 μm to 0.3 μm.

8. The display device as claimed in claim 1 , wherein the light-shielding conductive layer includes a light-shielding metal layer that contacts the first electrode, and a transparent conductive material layer on the light-shielding metal layer.

9. The display device as claimed in claim 1 , wherein the light-shielding conductive layer has a concentration gradient of a metal material and a transparent conductive material.

10. The display device as claimed in claim 1 , further comprising:

a passivation layer on the light-shielding conductive layer; and

a spacer disposed on the passivation layer and overlapping the switch.

11. The display device as claimed in claim 10 , wherein the spacer includes a light-shielding material.

12. The display device as claimed in claim 1 , further comprising:

a voltage line on the first base substrate; and

a connecting electrode directly contacting the voltage line,

wherein the first electrode is electrically connected to the connecting electrode.

13. The display device as claimed in claim 12 , wherein the connecting electrode includes the same material as the second electrode.

14. The display device as claimed in claim 1 , further comprising:

a voltage line on the first base substrate,

wherein the first electrode directly contacts the voltage line.

15. The display device as claimed in claim 1 , further comprising:

a voltage line on the first base substrate,

wherein the light-shielding conductive layer directly contacts the voltage line.

16. The display device as claimed in claim 1 , wherein the light-shielding conductive layer and the second electrode do not overlap each other where they overlap the switch.

17. The display device as claimed in claim 1 , further comprising a contact hole, which at least partially exposes the switch through the insulating layer, wherein the second electrode overlaps the switch only in the contact hole.
