Display panel having inclined edge defined by respective end surfaces of base substrate and insulating layer, and display device including the same

A display device, comprising:

• a display panel including:
• a display region including a pixel, and
• a pad region which is adjacent to the display region and defines an inclined edge of the display panel which is furthest from the display region and exposed outside the display panel;
• an electronic component connected to the display panel at the pad region thereof;
• and
• a conductive adhesion film which electrically connects the electronic component to the display panel at the pad region thereof,
• wherein the display panel comprises:
• a base substrate defining an end surface of the base substrate which is furthest from the display region and exposed outside the display panel;
• an insulating layer in the display region and the pad region;
• and
• in the pad region:
• a signal pad electrically connected to the pixel;
• a dummy pad electrically connected to the signal pad;
• the insulating layer which covers the signal pad and the dummy pad and defines an end surface of the insulating layer which is furthest from the display region and exposed outside the display panel, and
• a first opening in the insulating layer which exposes the signal pad to outside the insulating layer and to outside the display panel,
• wherein, in the pad region, the end surface of the base substrate and the end surface of the insulating layer together define the inclined edge of the display panel.
