摘要： A liquid crystal display device prevents the gray level folding in at least one of the vicinities of the highest and lowest gray levels while avoiding the complication of the data line driver circuit. The data line driver circuit generates output voltages whose number is equal to a predetermined gray level number M based on reference voltages, and selects one of the output voltages and outputs the selected one to the display section in response to an inputted image signal, thereby displaying images The applied voltage-brightness characteristic of the display section has a zero brightness change region in which the reference voltage corresponding to the highest gray level is located. The reference voltage corresponding to the next lower level to the highest level is set such that the brightness at the next lower level is lower than that at the highest level by a predetermined difference.
