A pixel detection device includes a substrate. Substrate includes a sub-pixel circuit, a detection transistor, and two second detection boards. Sub-pixel circuit includes a light emitting element. First detection board is coupled to detection transistor. Second detection board is coupled to light emitting element. First detection board outputs a first detecting signal in a sub-stage of a stage, and first detecting signal is switched from a first voltage level to a second voltage level to control a first voltage of detection transistor. Second detection board outputs a second detecting signal at sub-stage, and second detecting signal is switched from second voltage level to first voltage level to control a second voltage of first light emitting element. Detection transistor and light emitting element are conducted according to first voltage and second voltage to light up light emitting element, so as to detect whether brightness of light emitting element is abnormal.
