Abstract
A display device includes: a display panel; a main wiring board; a first wiring board that includes a first feedback line; and a first cable that is removably coupled to the main wiring board and the first wiring board. The main wiring board includes: a first output line; a first input line; a first circuit (a power supply circuit) that outputs a first voltage to the first output line; and a control circuit that is connected with the first input line. The first cable includes: a first forward conductor that directly or indirectly connects the first output line and the first feedback line; and a first return conductor that directly or indirectly connects the first input line and the first feedback line. The control circuit determines whether the first voltage is input, and when an input of the first voltage is determined, starts a display on the display panel.
