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.
