DISPLAY PANEL, INSPECTING METHOD AND MANUFACTURING METHOD FOR DISPLAY PANEL |
| 摘要 |
PROBLEM TO BE SOLVED: To provide an inspecting method of a display panel, which can discriminate whether an EL panel is non-defective or defective before the display panel is sealed. SOLUTION: The method has a fist inspecting method for patterning a conductive film and forming a pixel electrode after a process for measuring the value of a current flowing in the conductive film and detecting a defective pixel by the measured value and a second inspecting method for removing a conductive film for inspection after a process for connecting all the pixel electrodes with the conductive film for inspection, measuring the value of the current flowing in the conductive film for inspection and detecting the defective pixel by the measured value. |
