Abstract: The present disclosure relates to a display device including a process key, and more particularly, to a process key with an improved recognition rate in a display device implementing a narrow bezel. The feature of the present disclosure is such that a process key is divided into and formed as a first key pattern made of a metal material and a second key pattern made of a black matrix material, and the process key is positioned in a green pixel area in which a green color filter pattern is provided among pixels positioned at outermost peripheries corresponding to four corners of an active area of a display panel such that a narrow bezel can be implemented and a recognition rate of the process key can also be improved. Consequently, the display panel can be accurately aligned with manufacturing equipment or other objects such that a process defect can be minimized and process efficiency cab also be improved. Further, the process key can be recognized from both upper and lower sides of the display panel so that the process can be improved.

Abstract: Provided are a display device and a method of manufacturing the same. A display device includes: a first substrate and a second substrate spaced apart from and facing each other, a seal pattern on the first substrate at an edge between the first and second substrates, a gate insulating pattern including an inorganic insulating material, the gate insulating pattern directly contacting the seal pattern on the first substrate, and a protective film including an organic insulating material and including an etched groove through which the gate insulating pattern is exposed.
