Abstract

A display apparatus includes a first pixel and a second pixel adjacent to each other, wherein a first channel region of a driving transistor of the first pixel has a reverse U-shaped pattern, and a second channel region of a driving transistor of the second pixel has a pattern opposite the pattern of the first channel region.

Claims (20)

1. A display apparatus comprising:

a first pixel;

a second pixel, wherein the first pixel and the second pixel are adjacent to each other;

a power electrode between the first pixel and the second pixel, wherein the power electrode comprises a first electrode and a second electrode;

a first channel region of a driving transistor of the first pixel comprises a curved pattern; and

a second channel region of a driving transistor of the second pixel has a pattern opposite the pattern of the first channel region,

wherein a first node connecting the first electrode and the first channel region, and a second node connecting the second electrode and the second channel region do not face each other.

2. The display apparatus of claim 1 , wherein an end of the first electrode and an end of the second electrode are connected to each other.

3. The display apparatus of claim 1 , wherein the first electrode and the second electrode face each other.

4. The display apparatus of claim 1 , wherein the power electrode has a U-shaped pattern.

5. The display apparatus of claim 4 , wherein a power voltage is supplied to the power electrode from a power line connected to a center portion of the U-shaped pattern.

6. The display apparatus of claim 4 , wherein the power electrode comprises:

a first transistor between the first node and the center portion; and

a second transistor between the second node and the center portion.

7. The display apparatus of claim 6 , wherein the first transistor controls supply of the power voltage to the first node, and the second transistor controls supply of the power voltage to the second node.

8. The display apparatus of claim 1 , wherein a pattern of the power electrode is bisymmetrical.

9. The display apparatus of claim 1 , wherein

the first electrode and the second electrode face each other between the first pixel and the second pixel.

10. The display apparatus of claim 1 , wherein the pattern of the first channel region of the first pixel is bisymmetrical, and the pattern of the second channel region of the second pixel is bisymmetrical.

11. The display apparatus of claim 1 , wherein the curved pattern of the first channel region of the first pixel is a reverse U-shaped pattern.
