主权项

1. An electroluminescence display device comprising a plurality of pixel circuits and a pixel driving circuit,
wherein each of the plurality of pixel circuits includes an electroluminescence element, and wherein in a layout pattern of the pixel driving circuit:
an output line is electrically directly connected to a first source/drain region of a first transistor of a buffer circuit and a first source/drain region of a second transistor of the buffer circuit, a row of pixel circuits being electrically directly connected to said output line;a different output line is electrically directly connected to a first source/drain region of a third transistor of a different buffer circuit and a first source/drain region of a fourth transistor of the different buffer circuit, a different row of pixel circuits being electrically directly connected to said different output line;a high-potential power supply line is electrically directly connected a second source/drain region of the first transistor to a second source/drain region of the third transistor, said high-potential power supply line not crossing said output line or said different output line;a low-potential power supply line is electrically directly connected a second source/drain region of the second transistor to a second source/drain region of the fourth transistor, said low-potential power supply line not crossing said output line or said different output line, wherein the high-potential power supply line and the low-potential power supply line are extending in a column direction, and wherein the high-potential power supply line and the low-potential power supply line are disposed on an input side of the buffer circuit.
