IMAGE DISPLAY APPARATUS

Abstract

An image display apparatus is provided. At least one heat radiating frame is stacked in a heat radiating frame coupled between a circuit board and a panel, a heat radiating frame to which the circuit board is fixed can secure a space by a height of a protruded part as the protruded part is formed by drawing the frame itself, and thus fastening means for fixing the circuit board without a PEM nut can be fastened, and as a sound absorbing material is filled within a protruded part formed in a heat radiating frame opposite to the panel, vibration noise generating when driving the panel can be reduced.
