Embodiment Construction

[0043] Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

[0044] figure 1 is a plan view showing a display device according to an embodiment.

[0045] refer to figure 1 , the display device may include a display area DA in which an image is displayed and a peripheral area PA as a non-display area surrounding and adjacent to the display area DA.

[0046] The display area DA may be disposed on a plane formed by a first direction D1 and a second direction D2 perpendicular to the first direction D1. The display device may include a plurality of pixels P, a plurality of data lines, and a plurality of scan lines. Pixels P may be disposed in the display area DA, and may be disposed in a matrix to display images. Each of the pixels P may include a thin film transistor. The data line may be electrically connected to the pixel P. The scan lines may cross the data lines.

[0047] The peripheral area PA may be ...

Abstract

A display device comprises: a base substrate including a display area in which an image is displayed and a peripheral area which is a non-display area adjacent to the display area; a plurality of pixels which are arranged within the display area on the base substrate and each of which includes a thin film transistor including an oxide semiconductor pattern; a data driving unit disposed within the peripheral area and providing a data voltage to the pixels; and a plurality of test patterns which are arranged within the peripheral area on the base substrate and each of which includes a test thin film transistor including a test oxide semiconductor pattern.

Description

technical field [0001] The present invention relates to a display device. More specifically, the present invention relates to a display device with improved display quality. Background technique [0002] In recent years, display products having high performance are being produced as display products become smaller and lighter due to technological progress. Until now, since cathode ray tube (CRT) televisions have many advantages in terms of performance and price, CRT televisions have been widely used as display devices. However, recently, display devices (such as plasma display devices, liquid crystal display devices, organic light-emitting display devices, etc.) equipment, etc.) is drawing attention. [0003] In the manufacturing process of display devices, it is necessary to measure the thickness, resistance, concentration, pollution degree, critical dimensions and electrical characteristics of components (such as thin film transistors, etc.) of each process result to ch...
