## Abstract

A display apparatus includes a plurality of pixels arranged in rows and columns, each pixel column extends in a first direction and each pixel row extends in a second direction crossing the first direction, a first data line extending in the first direction and configured to transfer a data voltage to pixels included in at least two pixel columns, and for each pixel row, a first gate line extending in the second direction and disposed at a first side of the pixel row, and a second gate line extending in the second direction and disposed at a second side of the pixel row, the first and second sides of the pixel row are opposite to each other. In a pair of adjacent pixel columns, pixels, which are connected to the first gate line of their respective pixel row, are arranged in a zigzag arrangement in the first direction.

## Claims

### Claim 1

A display apparatus, comprising:
a plurality of pixels arranged in rows and columns, wherein each pixel column extends in a first direction and each pixel row extends in a second direction crossing the first direction;
a first data line extending in the first direction and configured to transfer a data voltage to pixels included in at least two pixel columns;
a second data line adjacent to the first data line;
a first pixel row includes a first pixel and a second pixel, the first and second pixels being disposed between the first data line and the second data line;
a second pixel row includes a third pixel and a fourth pixel, the third and fourth pixels being disposed between the first data line and the second data line, and the second pixel row is adjacent to the first pixel row, wherein the second pixel is disposed adjacent to the second data line and connected to the first data line, and the third pixel is disposed adjacent to the first data line and connected to the first data line;
for each pixel row, a first gate line extending in the second direction and disposed at a first side of the pixel row; and
a second gate line extending in the second direction and disposed at a second side of the pixel row, wherein the first and second sides of the pixel row are opposite to each other,
wherein, in a pair of adjacent pixel columns, pixels, which are connected to the first gate line of their respective pixel row, are arranged in a zigzag arrangement in the first direction.

### Claim 2 (depends on 1)

The display apparatus of claim 1,
wherein the first pixel is connected to the first or the second data line through a first data connection line and the second pixel is connected to the first or the second data line through a second data connection line, wherein a length of the second data connection line is equal to a length of the first data connection line.

### Claim 3 (depends on 2)

The display apparatus of claim 2, wherein the third pixel is connected to the second data line through a third data connection line and the fourth pixel is connected to the second data line through a fourth data connection line.

### Claim 4 (depends on 3)

The display apparatus of claim 3, wherein the third pixel and the fourth pixel have data connection lines that are a same length and wherein each is connected an upper side gate line.

### Claim 5 (depends on 3)

The display apparatus of claim 3, wherein the first and third pixels are included in a first pixel column, the second and fourth pixels are included in a second pixel column, and the first, second, third and fourth pixels respectively include first, second, third and fourth transistors, wherein the first and second transistors are disposed adjacent to a boundary area between the first and second pixel columns, and wherein the first pixel and the third pixel have data connection lines of different lengths.

### Claim 6 (depends on 3)

The display apparatus of claim 3, wherein the first and second data lines receive data voltages of different polarities from each other, and the data voltages charged in the plurality of pixels have a polarity inversion pattern of a (2 by 1) type, wherein, when the first pixel is disposed in a same pixel column as the third pixel, the (2 by 1) type of polarity inversion pattern indicates that the second and the third pixels have a first data voltage polarity during a first frame, and that the first and fourth pixels have a second data voltage polarity, opposite to the first data voltage polarity, during the first frame.

### Claim 7 (depends on 2)

The display apparatus of claim 2, wherein the first pixel is connected to the second data line through the first data connection line, and the fourth pixel is connected to the second data line through a fourth data connection line.

### Claim 8 (depends on 7)

The display apparatus of claim 7, wherein the first and second data lines receive data voltages of different polarities from each other, and the data voltages charged in the plurality of pixels have a polarity inversion pattern of a (1 by 1) type, wherein, when the first pixel is disposed in a same pixel column as the third pixel, the (1 by 1) type of polarity inversion pattern indicates that the first and fourth pixels have a first data voltage polarity during a first frame, and that the second and third pixels have a second data voltage polarity, opposite to the first data voltage polarity, during the first frame.
