摘要： The display device of this invention, in which the retaining circuit for retaining the image signal is provided for each of the pixel elements, is capable of operating under two operation modes, a normal operation mode and a memory mode. Since the placement of the retaining circuit 110, which requires relatively large area, is confined to the area for the pixel element electrode 17 not in between the neighboring pixel element electrodes 17, the required area for one pixel element is minimized, resulting in the size reduction of the liquid crystal display device. By placing at least a portion of the retaining circuit in the area of the pixel element electrode 17 of the neighboring pixel element, the detour of the wiring can be omitted, resulting in the efficient use of the space. By this, the area required for the retaining circuit is minimized, directly resulting in the reduction of the size of the liquid crystal display device.

摘要： An active matrix display device employing a top gate type TFT structure has a storage capacitor Csc and a liquid crystal capacitor Clc in each pixel of a pixel section, a first electrode of the storage capacitor Csc served by a p-Si active layer of the TFT, and a second electrode formed to at least partly overlap the active layer, with an insulating layer between the active layer and the second electrode below it. When a driver section is to be built in, the driver section TFT is the same top gate type as the pixel section TFT, and an active layer is made of the same material as the active layer and has a conductive layer which is made of the same material as the second electrode with the insulating layer held between the active layer and the conductive layer below it. The pixel section can form the storage capacitor while preventing lowering of the aperture ratio. Because conditions for the polycrystalization annealing of the active layer are equal for the pixel section TFT and the driver section TFT, TFTs with the same properties can be obtained.

摘要： Regarding an element having a channel width W greater than a pitch P of a pulse laser beam, a direction of the channel width W of a channel region CH is inclined with respect to a direction of a major axis of a line beam LB. Consequently, even if a defective crystallization region R is caused by an nonuniform intensity of an irradiated region in laser annealing forming p-Si of a p-Si TFT LCD, the whole channel width W of the channel region CH does not overlap the defective crystallization region R. Therefore, even if the defective crystallization region R is generated, element characteristics are not affected. Thus, the manufacturing yield of an excellent p-Si LCD can be enhanced.

摘要： In the display device having the retaining circuit for holding the digital image data at the pixel element, the power voltage supplied to the retaining circuit 110 is set up to be at the minimum level for the retaining circuit to hold the data during the data writing period, but the voltage supplied to the retaining circuit is raised by the voltage booster 95 upon the completion of the data writing. The retaining circuit 110 takes in the digital image signal fed from the drain signal line 61 in response to the signal fed from the gate signal line 51 and holds the digital image signal. Then, the display is carried out according to the signal held by the retaining circuit 110. By this, the erroneous writing of the data to the retaining circuit is prevented. The reduction of the electric power consumption and the high density integration of the pixel elements are also possible.

摘要： A voltage boosting circuit performs variable frequency control that gradually increases frequencies of clock signals from a low frequency to a high frequency during a boosting operation period for which a low output voltage of a DC-DC converter when the power is turned on is boosted up to a predetermined voltage. Thus, the frequencies of clock signals may be set according to the boosting operation of the DC-DC converter. Consequently, the operation of the DC-DC converter may be stabilized until the stable operation period is performed after the DC-DC converter starts to operate.

摘要： The active matrix display device has a thin film transistor and a pixel electrode, which is provided with a pixel voltage through the thin film transistor, for each of pixels. A supplemental pixel electrode, which is connected to the pixel electrode of one of the pixels adjacent to each other, and which extends to the region between the two pixels adjacent to each other, is also disposed. The supplemental pixel electrode enables the region between the pixels to be used as a part of the display region. The liquid crystal of this region is also driven by the voltage same as the pixel electrode. The configuration of the peripheral circuit of the pixel portion is simplified, reducing the framing area of the panel.
