A display device in which the first type of pixel and the second type of pixel are alternately arranged in a first direction in each of the plurality of pixel rows. In claim 13,
Each pixel row is:
a first subpixel row in which green light-emitting areas of the first type pixel and red and blue light-emitting areas of the second type pixel are alternately arranged in the first direction; and
A display device comprising a second subpixel row in which red and blue light-emitting areas of the first type pixel and green light-emitting areas of the second type pixel are alternately arranged in the first direction. In claim 1,
The plurality of pixels include a plurality of pixel columns in which the first pixel column and the second pixel column are alternately arranged in a first direction,
The first pixel column includes a plurality of first type pixels arranged in a second direction,
The second pixel column includes a plurality of second type pixels arranged in the second direction. In claim 15,
The first pixel row is,
a first subpixel row in which red light-emitting areas of the first type pixels are arranged in the second direction;
a second subpixel row in which green light-emitting areas of the first type pixels are arranged in the second direction; and
A display device comprising a third subpixel row in which blue light-emitting areas of the first type pixels are arranged in the second direction. In claim 15,
The second pixel row is,
a first subpixel row in which red light-emitting areas of the second type pixels are arranged in the second direction;
a second subpixel row in which green light-emitting areas of the second type pixels are arranged in the second direction; and
A display device comprising a third subpixel row in which blue light-emitting areas of the second type pixels are arranged in the second direction. Includes a pixel array area where a plurality of pixels are arranged,
Each of the plurality of pixels includes a red light-emitting area, a green light-emitting area, and a blue light-emitting area having different areas,
The plurality of pixels include a first type of pixel arranged in odd pixel columns and a second type of pixel arranged in even pixel columns,
The first type of pixel is arranged in a clockwise triangular structure and includes a first red light-emitting region, a first green light-emitting region, and a first blue light-emitting region having different areas,
The second type of pixel is arranged in a semi-clockwise inverted triangle structure and includes a second red light-emitting region, a second green light-emitting region, and a second blue light-emitting region having different areas,
A display device in which the red light-emitting area has the smallest area and the blue light-emitting area has the largest area in each pixel. In claim 18,
In each pixel,
The area ratio of the red, green, and blue emission areas is in the range of 1:3 to 4:5 to 6,
Among the red, green, and blue light emitting regions,
The green light-emitting area has the same or different shape from other light-emitting areas,
A display device wherein the red light-emitting area and the blue light-emitting area have the same shape, but have a left-right inverted structure. In claim 19,
The green light-emitting area has a rhombus shape or a rhombus shape with corners cut,
The red light-emitting area and the blue light-emitting area have a diamond shape, a diamond shape with corners cut, a trapezoid shape, a triangle shape, or a triangle shape with corners cut.
