Abstract: A current limiting circuit is used in a display device which includes a display panel having pixels each of which includes a light emitting element and a panel power source which supplies an application voltage to be applied to each of the light emitting elements included in the pixels. The current limiting circuit detects a supply current supplied from the panel power source to the display panel, and reduces the application voltage when a value of the supply current detected is greater than a threshold.

Abstract: A printed board has an elongated shape and is to be electrically coupled to a display panel via a flexible board. The printed board includes a first board section; and a second board section shorter in length than the first board section in a substantially perpendicular direction to a longitudinal direction of the printed board. The first board section and the second board section are disposed in a row in the longitudinal direction, each of the first board section and the second board section has a first end in the substantially perpendicular direction to the longitudinal direction, the first end of the first board section projects further than the first end of the second board section in the substantially perpendicular direction, and a connection portion to be connected to the flexible board is disposed at the first end of each of the first board section and the second board section.
