Abstract

A display apparatus for vehicles is provided. The display apparatus for vehicles comprises a disc player comprising a display mounting unit, wherein a connection plate of a display unit is coupled to the bottom surface of the display mounting unit in a stacked form, or separated from the bottom surface; the display unit which comprises the connection plate having second fixing parts enabling the display unit to be coupled with the display mounting unit in a stacked form facing each other, and a screen unit which is installed on the connection plate through a hinge so as to rotate about the hinge, is capable of being folded and unfolded; and fixing components which allow the disc player and/or the display unit to be fixed to the ceiling of the vehicle. The display apparatus allows a purchaser to select a disc player as an option item and easily replace only a defective part. Particularly, the display apparatus has an advantage of easy installation and separation.
