摘要： There is disclosed an active matrix liquid crystal display that receives input signals having small amplitudes and needs no externally attached level-shifting circuit. The active matrix liquid crystal display has a level-shifting circuit for amplifying various input signals, such as control signals, a clock signal, and a start pulse signal, and supplying the amplified signals to peripheral driver circuits. These peripheral driver circuits drive an active matrix circuit. The level-shifting circuit is made of a differential amplifier consisting of polysilicon TFTs. This amplifier is an analog amplifier. This level-shifting circuit is fabricated on the same substrate as the active matrix circuit and the peripheral driver circuits. If the amplitudes of the input signals are small, level-shifting operations can be performed well. Since any externally attached level-shifting circuit is dispensed with, the cost can be curtailed.

摘要： An image display device includes an operational amplifier, a signal amplifier provided with a condenser for setting a gain of the operational amplifier, a signal amplifier circuit having such signal amplifier or a buffer amplifier, the signal amplifier circuit being provided with an offset adjusting function, and a data signal line drive circuit having a signal amplifier or a signal line drive circuit. The described arrangement enables the gain of the signal amplifier to be set by a capacitance of the condenser, thereby providing a signal amplifier circuit which permits the gain to be set much more precisely as compared to the conventional signal amplifier circuits even when adopting a signal amplifier formed on a semiconductor thin film such as a polycrystalline silicone thin film. The arrangement also provides a signal amplifier circuit which permits a voltage in the same level as a voltage of the input signal to be outputted. Furthermore, the arrangement provides high quality data signal line drive circuit and the image display device.

摘要： An active-matrix image display device which includes n shift registers, analog switches for sampling video input signals and a data-signal-line driving circuit to which n series of clock signals and n.times.m series of video input signals are input, and controls the analog switches according to the result of a logic operation of output pulses from successive l stages in the shift registers. A scanning circuit without using shift registers. Here, n is an integer not smaller than one, m and l are integers not smaller than two. With the image display device, sampling of video signals is surely executed without increasing the number of shift registers. It is thus possible to reduce the size and weight of the image display device and to decrease the defect rate thereof. Moreover, the scanning circuit achieves a higher yield compared with a conventional scanning circuit using a shift register.
