Abstract

A display device includes a first active pattern disposed on a substrate, a first gate electrode disposed on the first active pattern, a second active pattern disposed on the first gate electrode, being electrically connected to the first gate electrode, and including an extension part extending in a first direction and a protrusion part protruding from the extension part in a second direction crossing the first direction, and a voltage line disposed on the second active pattern, extending in the first direction, and overlapping the protrusion part in an overlapping region. The voltage line contacts the protrusion part through a first contact, and the first contact entirely overlaps the overlapping region on a plane.

Description

technical field [0001] Exemplary embodiments / implementations of the present invention generally relate to display devices. Background technique [0002] A display device includes a display panel and a panel driver (eg, a data driver, a gate driver, etc.) that drives the display panel. A plurality of conductive patterns are sequentially formed on the display panel, and the conductive patterns may be contacted through the contact holes. The panel driver provides signals and / or voltages to conductive patterns of the display panel. The conductive pattern is patterned to have a repeated unit structure on a plane, and a conductive pattern having one unit structure among the unit structures may be defined as a pixel structure. Meanwhile, contact resistance may occur between conductive patterns contacted through the contact holes. As the distribution of contact resistance increases, the distribution of electrical characteristics of the pixel structure may increase. This results ...
