Circuit board and display device

摘要

A display device and a circuit board for it are provided. The circuit board includes a bare copper region which is positioned corresponding to a chip of a driver IC of the display device; the bare copper region resists the chip and is configured to conduct away the heat generated from the chip. The display device comprises a circuit board, a driver IC electrically connected to the circuit board and fixed on the circuit board, and a display screen electrically connected to the driver IC. The following advantageous effects can be achieved: the circuit board has a bare copper region resisting the chip of the driver IC, which can effectively conduct away the heat generated from the driver IC to make the heat-dissipating effect of the display device better, and thereby extending the lifetime of the display device.
