摘要： A liquid crystal display that is unsusceptible to the effect of a pixel potential during writing of data to a memory, allowing a large margin to be provided against variation in characteristics of transistors forming a pixel circuit, and a portable terminal having the liquid crystal display. In a pixel circuit including a memory circuit (25), separate paths are provided for writing image data from a signal line (16-i) to the memory circuit (25) via a data-write switch (24) and for reading image data held in the memory circuit (25) out into a liquid crystal cell unit via a data-read switch (27). Furthermore, image data are read via a data-read buffer (26). Accordingly, when image data is written to the memory, data held in the memory circuit (25) is not affected by a pixel potential. Thus, a large margin can be provided against variation in the characteristics of the transistors forming the pixel circuit, serving to avoid variation in picture quality due to the variation in the transistor characteristics.

摘要： An active-matrix liquid crystal display device has pixels arranged in a matrix which each include a thin film transistor (TFT) as an active element. When the device is in a power-off state, TFTs in all the pixels are switched on, and all horizontal switches are turned on so that all data lines are supplied with a potential equal to the potential of common electrodes of the pixels. This forms a discharging path for discharging residual charge in all the pixels, and the discharging path can instantaneously discharge the residual charges.
