The embodiments of the invention provide an image processing device and liquid crystal display equipment. The image processing device is used for solving the problem in the prior art that a read/write circuit, which connects an image amplifying chip with a reading/writing tool, can only carry out reading/writing on a whole register or a certain segment of the register singly. The device comprises the image amplifying chip, a transmission circuit, a directly-connected circuit, a phase inverting circuit, a control circuit and the reading/writing tool, wherein the control circuit is used for controlling an image signal port of the image amplifying chip to be connected or disconnected with the directly-connected circuit, controlling a clock signal port of the image amplifying chip to be connected or disconnected with the directly-connected circuit, controlling the image signal port of the image amplifying chip to be connected or disconnected with the phase inverting circuit, and controlling the clock signal port of the image amplifying chip to be connected or disconnected with the phase inverting circuit.
