ABSTRACT:
A liquid crystal display apparatus which exhausts heat generated within the apparatus efficiently, and reduces temperature increase in the heat-frail sections is provided.A circuit board mounting surface at the back of the liquid crystal monitor unit is divided into a plurality of board mount areas using the vertically extending reinforcement members. A signal circuit board section and TCON (Timing control) circuit board section are disposed in the same board mount area which is different from the partition where the power supply circuit board section resides. By arranging this way, the temperature increase in the heat-frail sections of the signal circuit board section is reduced, and the hot air heated by the power supply circuit board in the power supply circuit board section goes up along the reinforcement members, thus an efficient heat exhaustion is achieved.
