发明名称 METHOD FOR MANUFACTURING ELECTROLUMINESCENT DISPLAY DEVICE
摘要 A plurality of pixels arranged in a matrix each include an EL element, a transistor, and a transistor. The EL element includes a cathode to which a first voltage is applied. The transistor includes a gate connected to a gate signal line, a source connected to an anode of the EL element, and a drain to which a second voltage having a potential higher than a potential of the first voltage is applied. A method for manufacturing the EL display device includes: applying the second voltage to the anode of the EL element via the transistor, by applying an ON voltage to the gate signal line; and detecting light emission by the EL element, using an optical detector, in a state in which the ON voltage is being applied to the gate signal line.
