PURPOSE: To provide the liquid crystal display module which can realize both of adjustment of contrast of a liquid crystal display panel and adjustment of brightness of a back light without obstructing miniaturization of a product and a decrease of the manhour of assembly, at the time of integrating the module into the product.

CONSTITUTION: In the liquid crystal display module provided with a liquid crystal display panel 2, a driver IC and a printed board 3 having a bus line for supplying a power source and a signal to the driver IC, and constituted by connecting electrically and mechanically the liquid crystal display panel 2 and the driver IC, and the driver IC and the printed board 3, respectively and containing them in a bezel 6, this liquid crystal display module is constituted by providing a panel contrast adjustment variable resistor 4 for adjusting contrast of the liquid crystal display panel 2, and a back light brightness adjustment variable resistor (omitted in the figure) for adjusting brightness of a back light, in the module.
