## Abstract

A display device and method of fabricating the same are disclosed. In one aspect, the display device includes a substrate, a black matrix formed over the substrate, and a transparent electrode formed over the substrate. The black matrix and the transparent electrode have first and second areas, respectively. The sum of the first and second areas is substantially equal to the surface area of the substrate.

## Claims

### Claim 1

A display device, comprising:
a substrate;
a gate pattern including i) a gate electrode formed over the substrate, ii) a gate line extending in a first direction, and iii) a gate pad formed at one end of the gate line;
a data pattern including i) a semiconductor pattern at least partially overlapping the gate electrode, ii) a source electrode contacting a portion of the semiconductor pattern, iii) a drain electrode contacting another portion of the semiconductor pattern and spaced apart from the source electrode, iv) a data line extending in a second direction crossing the first direction, and v) a data pad formed at one end of the data line;
a black matrix formed over the substrate and having a first area; and
a transparent electrode formed over the substrate and having a second area,
wherein the sum of the first and second areas is substantially equal to the surface area of the substrate.

### Claim 2 (depends on 1)

The device of claim 1, wherein the substrate comprises at least one display area configured to display an image and at least one non-display area.

### Claim 3 (depends on 2)

The device of claim 2, wherein the black matrix comprises a plurality of portions formed in the non-display area.

### Claim 4 (depends on 3)

The device of claim 3, wherein the transparent electrode comprises a plurality of portions formed in the display area and the remaining portions of the non-display area.

### Claim 5 (depends on 1)

The device of claim 1, further comprising:
a first insulating layer formed between the gate pattern and the data pattern; and
a second insulating layer formed over the first insulating layer.

### Claim 6 (depends on 5)

The device of claim 5, wherein a contact hole overlapping a portion of the gate pad is formed in the first and second insulating layers,
wherein a drain contact hole overlapping a portion of the drain electrode and a data contact hole overlapping a portion of the data pad are further formed in the second insulating layer.

### Claim 7 (depends on 6)

The device of claim 6, wherein the transparent electrode comprises:
a pixel electrode electrically connected to the drain electrode via the drain contact hole;
a gate pad electrode electrically connected to the gate pad via the gate contact hole; and
a data pad electrode electrically connected to the data pad via the data contact hole.

### Claim 8 (depends on 1)

### Claim 9 (depends on 1)

The device of claim 1, wherein the first area comprises a projection onto the substrate and wherein the second area comprises a projection onto the substrate.

### Claim 10

A display device, comprising:
a substrate;
a black matrix formed over the substrate and having a first area; and
a transparent electrode formed over the substrate and having a second area,
wherein the sum of the first and second areas is substantially equal to the surface area of the substrate.

### Claim 11 (depends on 10)

The device of claim 10, wherein the first area comprises a projection onto the substrate and wherein the second area comprises a projection onto the substrate.

### Claim 12 (depends on 10)

The device of claim 10, wherein the substrate comprises at least one display area configured to display an image and at least one non-display area, and wherein the black matrix comprises a plurality of portions formed in the non-display area.

### Claim 13 (depends on 12)

The device of claim 12, wherein the transparent electrode comprises a plurality of portions formed in the display area and the remaining portions of the non-display area.
