Abstract: A display apparatus includes a display panel for reproducing an image or a video, a metal plate disposed in the rear of the display panel, a printed circuit board disposed in the rear of the metal plate and electrically connected to the display panel, and a chip-on-film having one end electrically connected to the display panel and the other end electrically connected to the printed circuit board, wherein a portion of the chip-on-film is bendable, and the metal plate includes a bending guide formed at a position corresponding to the bendable portion of the chip-on-film and guiding a bent shape of the chip-on-film. In the display apparatus according to the present disclosure, the bending guide disposed in a portion where the chip-on-film is bent may prevent a curvature of the chip-on-film from deviating from a designed range of the curvature, thereby suppressing excessive bending of the chip-on-film. For this reason, the chip-on-film may be effectively suppressed from being excessively bent and damaged.

Abstract: A display apparatus is disclosed that includes a display panel having front and rear surfaces; a heat dissipation plate having front and rear surfaces and the rear surface of the heat dissipation plate is on the rear surface of the display panel; a source printed circuit board on the rear surface of the heat dissipation plate, and connected to the display panel; a control printed circuit board on the rear surface of the heat dissipation plate and comprising a retaining protrusion that protrudes towards the rear surface of the display panel; and a holder member between the heat dissipation plate and the control printed circuit board and holding the control printed circuit board in the heat dissipation plate. The control printed circuit board is stably held and thus expected to have effects on reducing shaking during logistics transportation and simplifying a manufacturing process.
