Embodiment Construction

[0035] Hereinafter, a display device according to an embodiment will be explained in detail with reference to the accompanying drawings.

[0036] figure 1 is a plan view showing a display device according to an embodiment of the present disclosure.

[0037] refer to figure 1 , the display device may include pixels PX disposed in the display area DA, a scan driver SD disposed in the peripheral area PA, a driving chip IC, and a flexible printed circuit FPC.

[0038] The pixels PX may be arranged in the display area DA in a first direction DR1 and a second direction DR2 crossing the first direction DR1. Each pixel PX may be connected to a scan line SL, a data line DL and a driving voltage line PL. The scan line SL may extend in the first direction DR1 to provide scan signals to the pixels PX. The data line DL may extend in the second direction DR2 to supply the data voltage to the pixel PX. The driving voltage line PL may extend in parallel to the data line DL to supply a dr...

Abstract

Disclosed is a display device comprising a substrate, a barrier layer disposed on the substrate and having a trench, an active pattern disposed on the barrier layer, formed of an oxide semiconductor, and including a channel region protruding downward along a profile of the trench, and a source region and a drain region disposed at each end of the channel region, respectively, a gate electrode disposed on the active pattern and overlapping the channel region, a source electrode disposed on the gate electrode and electrically connected to the source region, and a drain electrode disposed on the gate electrode and electrically connected to the drain region.

Description

technical field [0001] The present disclosure relates to display devices. More particularly, the present disclosure relates to a display device including a plurality of transistors with improved electrical characteristics. Background technique [0002] The importance of display devices has grown with the development of multimedia. Accordingly, various types of display devices such as liquid crystal displays (LCDs) and organic light emitting displays (OLEDs) are widely used in various types of electronic devices including portable devices such as smart phones, smart watches, or smart tablets. In general, a display device may include pixels and a driver for driving the pixels. Each of the pixels and drivers may include multiple transistors. [0003] As the resolution of a display device increases and the dead zone of the display device decreases, an area in which transistors are disposed may decrease. Therefore, electrical characteristics of transistors disposed in a relat...
