1. A display device comprising:
a pixel part including a plurality of pixels and disposed in a display area;
a demultiplexing circuit part disposed in a non-display area surrounding the display area and configured to transfer a data voltage to the pixel part; and
a connection pattern disposed in the non-display area, configured to transfer a constant voltage to the pixel part, and including a first portion overlapping the demultiplexing circuit part and a second portion disposed between the first portion and the pixel part,
wherein a plurality of first penetration holes vertically penetrating the first portion is formed in the first portion,
wherein a plurality of second penetration holes vertically penetrating the second portion is formed in the second portion,
wherein the demultiplexing circuit part receives the data voltage from a data driver, and the connection pattern receives the constant voltage from a power provider, and
wherein the plurality of first penetration holes extends to an upper surface of an insulating layer which is disposed under the first portion, and the plurality of second penetration holes extends to the upper surface of the insulating layer and a side surface of the insulating layer.
