Abstract

A liquid crystal module includes a rear frame, a lamp frame, a liquid crystal panel and a bezel. The rear frame has a bottom plate, a side plate and a flange. The flange has a first screw insertion hole. The lamp frame is fixedly attached to the rear frame along the side plate of the rear frame. The lamp frame has a lamp frame top plate that is disposed on the flange of the rear frame. The lamp frame top plate has a second screw insertion hole. The bezel is fixedly attached to the rear frame. The bezel has a bezel top plate that is disposed on the lamp frame top plate of the lamp frame. The bezel top plate has a third screw insertion hole. The first, second and third screw insertion holes are aligned each other as viewed from a center axis of the first screw insertion hole.
