Method of inspecting a display device and electronic device comprising the display device

A method of inspecting a display device, comprising:

• providing an inspection-target display device including a substrate including a first surface and a second surface, and a first sub-pixel and a second sub-pixel each formed on the first surface of the substrate and disposed adjacent to each other;
• performing an etching process directed in a direction from the second surface toward the first surface;
• and
• performing an inspection process on the first sub-pixel and the second sub-pixel,
• wherein the first sub-pixel includes a first anode electrode, and a first contactor electrically connected to the first anode electrode, and wherein the second sub-pixel includes a second anode electrode, and a second contactor electrically connected to the second anode electrode,
• wherein performing the etching process further comprises exposing the first contactor and the second contactor, and
• wherein performing the inspection process further comprises bringing a first probe into electrical contact with the first contactor and bringing a second probe into electrical contact with the second contactor.
