Abstract

A liquid crystal display includes a first substrate including: a display area including a plurality of pixels on the first substrate, a non-display area which is disposed on an outside of the display area and in which a dummy wire is disposed on the first substrate, and an image input hole which is defined therein in the non-display area and in which an image input device is disposed, a second substrate facing the first substrate and including a display area and a non-display area corresponding to those of the first substrate, a liquid crystal layer interposed between the first and second substrates, and a sealant which is in the non-display area of the first and second substrates and seals the liquid crystal layer between the first and second substrates. The dummy wire is disposed near the image input hole.

Claims (34)

1. A liquid crystal display comprising:

a first substrate comprising:

a display area in which an image is displayed, the display area including:

a plurality of pixels on the first substrate, and

a signal wiring through which signals for driving the pixels are transmitted, and

a non-display area which is disposed outside of the display area and in which the image is not displayed, the non-display area including:

an image input hole which is defined therein in the non-display area and in which an image input device is disposed, and

a dummy wire disposed a same distance from the first substrate as the signal wiring in the display area, the dummy wire corresponding to a location of the image input hole;

a second substrate facing the first substrate and comprising:

a display area corresponding to the display area of the first substrate and in which the image is displayed, and

a non-display area corresponding to the non-display area of the first substrate and in which the image is not displayed;

a liquid crystal layer interposed between the first and second substrates;

a sealant which is in the non-display area of the first and second substrates and seals the liquid crystal layer between the first and second substrates, and

a spacer which completely covers the image input hole and maintains a gap between the first and second substrates, the spacer being formed of a transparent material,

wherein the spacer which completely covers the image input hole further overlaps the dummy wire, side surfaces of the spacer directly contacting the sealant to be completely surrounded by the sealant.

2. The liquid crystal display of claim 1 , wherein the dummy wire includes aluminum, silver or copper.

3. The liquid crystal display of claim 1 , wherein the dummy wire is disposed adjacent to an outer edge of the image input hole.

4. The liquid crystal display of claim 3 , wherein the dummy wire forms a closed curve around the image input hole.

5. The liquid crystal display of claim 1 , wherein the dummy wire is provided in plural near the image input hole.

6. The liquid crystal display of claim 5 , wherein the plurality of dummy wires is spaced from one another by a predetermined distance.

7. The liquid crystal display of claim 5 , wherein the plurality of dummy wires is spaced from a center of the image input hole by a same distance.

8. The liquid crystal display of claim 5 , wherein among the plurality of dummy wires, with respect to the image input hole,

two opposing dummy wires are spaced from a center of the image input hole by a same distance, and

two non-opposing dummy wires are spaced from the center of the image input hole by different distances.

9. The liquid crystal display of claim 5 , wherein among the plurality of dummy wires, each two different dummy wires are spaced from a center of the image input hole by a same distance.

10. The liquid crystal display of claim 1 , wherein

the signal wiring of the display area includes gate wiring which is on the first substrate and through which the signals for driving the pixels are transmitted, and

the dummy wire is disposed a same distance from the first substrate as the gate wiring, to be disposed in a same layer as the gate wiring among layers disposed on the first substrate.

11. The liquid crystal display of claim 1 , wherein

the signal wiring of the display area includes data wiring which is on the first substrate and through which the signals for driving the pixels are transmitted, and

the dummy wire is disposed a same distance from the first substrate as the data wiring, to be disposed in a same layer as the data wiring among layers disposed on the first substrate.

12. The liquid crystal display of claim 1 , further comprising:

a light-shielding pattern disposed on the second substrate in the non-display area thereof,

wherein the light-shielding pattern is disposed non-overlapping the image input hole.
