Abstract: The present invention relates to a display apparatus that does not include a middle mold and a rear chassis, and is capable of supporting an internal configuration of a display apparatus such as a display panel and a light guide plate with only a front chassis and a rear cover. It is possible to effectively dissipate heat by including a separate heat sink. In addition, heat generated from the electrical component substrate can be dissipated through the plate coupled to the electrical component substrate, the electromagnetic wave can be shielded, and the heat sink and the plate can be connected to improve the heat dissipation and electromagnetic wave shielding efficiency.

Abstract: Provided is a display apparatus without a front chassis or a bezel. A front frame is provided on at least one side of a display panel to hide a chip-on-film and a printed circuit board coupled to the display panel that would be otherwise exposed to the outside. A front surface of the front frame may have a color and light reflectivity corresponding to those of a non-display area of the display panel. Thus, the display panel and the front frame may appear to be integrally formed. Accordingly, a bezel-less display apparatus, in which no bezel is formed around the display panel, may be achieved.
