とを特徴とする、液晶表示装置。[Claims for Utility Model Registration] A liquid crystal display that includes a liquid crystal display element, a drive control circuit that drives the liquid crystal display element to perform a desired display, and a drive power supply circuit that supplies a drive voltage to the drive control circuit. In the device, the driving power supply circuit includes a temperature sensor, a storage device in which temperature-driving voltage characteristics are stored in advance,
A predetermined drive voltage is read out according to the temperature-drive voltage characteristic stored in the storage device based on the input section to which the viewing angle adjustment is input and the input signal from the temperature sensor, and a corresponding digital signal is generated. It is composed of a central processing unit that outputs an output, and a DA conversion circuit that converts a digital signal from the central processing unit into the predetermined drive voltage, and when an adjustment input is received from the input section, the central processing unit The unit writes the read drive voltage changed based on the adjustment input into the storage device along with the temperature at that time, corrects the temperature-drive voltage characteristic, and adjusts the adjusted drive voltage. A liquid crystal display device characterized in that it outputs a digital signal corresponding to.
