Abstract:
1. A display device, comprising, a drive substrate; a counter substrate opposed to the drive substrate; an electro-optic material sealed between the drive substrate and the counter substrate; a plurality of source lines formed on the drive substrate; a plurality of gate lines formed on the drive substrate in an orthogonal manner to the source lines; a plurality of pixel electrodes formed near intersections of the plurality of source lines and the plurality of gate lines and applying electric charge outputted to the source lines to the electro-optic material; switching elements coupled to the gate lines and switching conduction states between the source lines and the pixel electrodes; a counter electrode formed on the counter substrate and coupled to the pixel electrodes; gate dummy pixels including: source dummy pixels including: a test switch line coupled to the gate switching elements and the source dummy switching elements and transmitting a control signal for controlling switching of the conduction states to the gate dummy switching elements and the source dummy switching elements; a plurality of test gate lines respectively coupled to the gate dummy pixel electrodes that are not adjacent to each other in such a manner that the gate lines provided with the gate dummy pixel electrodes are divided into two or more phases; and a plurality of test source lines respectively coupled to the source dummy pixel electrodes that are not adjacent to each other in such a manner that the source lines provided with the source dummy pixel electrodes are divided into two or more phases.
