There is a need for decreasing a variation in times for writing to TFT elements for pixels in a direction along the extension of a gate line in a liquid crystal display apparatus. A display apparatus includes a display panel having multiple gate lines and drain lines arranged in a matrix and a data driver for outputting a display data signal to each drain line. The data driver includes: an internal control signal generation circuit generating an internal control signal for setting a timing to output a data signal to a drain line of each block on a block basis by dividing the plurality of drain lines into multiple blocks; and a register circuit for recording a setting for division of the block, a setting for delay direction and width of a timing to output the data signal, and a setting for rising and falling of an internal control signal.

Display apparatus

A display device has a display panel having a first substrate for displaying an image that is observed from a front surface of the first substrate. A translucent substrate covers the display panel from the front surface of the first substrate. The translucent substrate has a rear surface and a first light shielding portion on a periphery of the rear surface. A photo-curable translucent adhesive integrally bonds a front surface of the first substrate and the rear surface of the translucent substrate to each other. A first light reflecting portion is formed on the first light shielding portion of the translucent substrate. A second light reflecting portion is formed on a surface of the first substrate so as to oppose the first light reflecting portion through the photo-curable translucent adhesive.

A display device includes a plurality of pixels and drive circuits which drive the plurality of pixels, wherein each drive circuit includes a first input/output terminal, a second input/output terminal, a scanning-direction changeover terminal, and a position designation terminal. In response to a voltage applied to the position designation terminal and a scanning-direction control signal applied to the scanning-direction changeover terminal, the scanning direction is switchable between the first scanning direction which acquires a start pulse from the first input/output terminal and outputs the start pulse from the second input/output terminal and the second scanning direction which acquires the start pulse from the second input/output terminal and outputs the start pulse from the first input/output terminal.

A liquid crystal display device which includes a first substrate, a second substrate, a liquid crystal composition sandwiched between the first substrate and the second substrate, and a plurality of pixels disposed on the first substrate. Each of the plurality of pixels is supplied with a video signal via a switching element. Each of the plurality of pixels is provided with a capacitance having two electrodes in which one is connected to a first electrode of a corresponding one of the plurality of pixels and another is supplied with a pixel-potential control signal by a pixel-potential control circuit. The pixel-potential control circuit enables selection of a first voltage level and a second voltage level.

Liquid crystal display device having a low-voltage driving circuit

An amplifier circuit in a display device for a monitor unit in a computer system or the like, includes first active element whose control electrode is supplied with a signal from an input terminal; a second active element cascade-connected to the first active element; a third active element so connected to the second active element that a junction thereof is connected to an output terminal; an impedance element disposed between the input terminal and the third active element and capable of changing the impedance in accordance with the frequency of the input signal; a first resistance element connected between the junction of the second and third active elements and the control electrode of the first active element; and a second resistance element connected between the input terminal and the control electrode of the first active element and serving to determine the signal amplification factor in cooperation with the first resistance element. Since the second active element is cascade-connected to the first active element, no manipulation is necessary for adjusting the component elements, and generation of any smear or sag resulting from variation of the feedback capacitance can be suppressed at low cost.
