Display panel, display panel inspection method, and display panel manufacturing method |
摘要 |
A method of inspecting a display panel, which is capable of distinguishing between whether an EL panel is a good product or a defective product before sealing of the display panel, is provided. In a first method of inspection, a conductive film is patterned to forming pixel electrodes after measuring the electric current flowing in the conductive film and detecting defective pixels in accordance with the measured values. In a second method of inspection, all of the pixel electrodes are connected by an inspection conductive film, a value of electric current flowing in the inspection conductive film is measured, and the inspection conductive film is removed after detecting defective pixels in accordance with the measured values.
