Problems solved by technology

[0005] However, the transistors inside the test element group are independent transistors, which cannot represent the overall connection of multiple transistors inside the display area.
Therefore, even if the transistors in the test element group are degraded by static electricity, the transistors in the display area can be driven normally, so there is a disadvantage that the transistors in the test element group cannot represent the transistors in the display area
[0006] As mentioned above, since the transistors inside the test element group are independent structures, it is impossible to monitor the protective film loading and unloading process, film scribing (scribing) process, laser lift off (Laser Lift Off, LLO for short) process and mold process of flexible display devices. Static electricity generated during the module process, etc.

Abstract

A display device according to an exemplary embodiment of the present invention includes a display portion including a plurality of display pixels displaying an image and a dummy portion including a plurality of dummy pixels formed in a periphery region of the display portion. An electrostatic test element group (TEG) may be formed in at least one of the dummy pixels.

Description

technical field [0001] The present invention relates to a display device, and more particularly to a display device for displaying images. Background technique [0002] In order to confirm whether the implementation results of each process of manufacturing the display device have reached a better state, it is necessary to measure the thickness, resistance, concentration, degree of contamination, critical value, and electrical characteristics of the device of each process result. Due to damage to the device, process characteristics may not be monitored on the actual substrate. [0003] In this case, a pattern called a Test Element Group (TEG) is formed on a specific portion of the substrate on which the device is formed or in another blank area and similarly performed on the substrate on which the actual device is formed. After the process performed on the substrate, the test element set is measured to evaluate the corresponding process. [0004] In order to monitor static ...
