A programmable logic IC and a ROM are set in a controller section between a display and ICs (an IC for wireless communication and an IF IC). In each of plural program sets stored in the ROM, a series of operation up to the time that image data, after being read from the IC for wireless communication and converted into a logic signal, is sent to the display is described. On the other hand, the programmable logic IC changes the program set being read, according to what is displayed on the display, television images, a monitor image supplied from a computer, or image data from a memory card. This makes it possible to attain an image-display-device controller circuit that has a small circuit scale, consumes a small amount of power, and is small in size and weight are small, but can change operation.

A liquid crystal display device has a liquid crystal layer between a glass substrate and a counter substrate. A TFT and scanning lines which control the TFT are provided on the glass substrate. On the counter substrate, a gradation signal line which is connected to a counter electrode applying a voltage to the liquid crystal layer is provided opposite to the scanning lines. A sealing section for sealing the liquid crystal of the liquid crystal layer is provided while enclosing the display area between the glass substrate and the counter substrate. The sealing section has conductive particles. Upper contact pads connected to the gradation signal lines and lower contact pads on the glass substrate are electrically connected via the conductive particles. This realizes a liquid crystal display device with a smaller frame and makes the mounting compact in size without causing poor connection due to line breakage.

A display device includes: a first substrate including data electrodes and first and second groups of connecting pads; a second substrate, which faces the first substrate and which includes data signal input terminals, a spare line, and third and fourth groups of connecting pads opposed to the first and second groups of connecting pads, respectively; and a display medium layer interposed between the first and second substrates. The data signal input terminals are connected to the third group of connecting pads. In case of disconnection, a data signal to be supplied to one of the data electrodes may be input through the spare line. The fourth group of connecting pads crosses the spare line with an insulating layer interposed between them. Each pair of connecting pads in the first and third groups or the second and fourth groups is electrically connected together with an anisotropic conductive material.

As a method of driving a liquid crystal display device, the average voltage of reference line drive voltages Vcom for AC-driving a liquid crystal is set higher than the average voltage of signal line drive voltage V0. Moreover, when displaying a plurality of gray scales, the respective voltages are set so that the average voltage of the signal line drive voltages is lowered with a decrease in a voltage difference to be applied to the liquid crystal as an absolute value. In a liquid crystal display device of an opposing signal line structure, a high-quality image display is achieved by compensating for the non-symmetry of the transmissivity of the liquid crystal with respect to positive and negative drive voltages to prevent flickering and image persistence.

An object of the present invention is to provide an active matrix type liquid crystal display apparatus, capable of being upsized and having enhanced resolution at low cost without being degraded in display quality. In the liquid crystal display apparatus, on a pixel substrate, scanning lines and reference signal lines are formed in a row direction, and on a counter substrate, gradation signal lines are formed in a column direction. A liquid crystal layer is sandwiched between the pixel substrate and the counter substrate. Outside an image display region, a reference signal transfer pad is disposed on the counter substrate opposite to a main reference signal line for connecting end portions of reference signal lines. The reference signal transfer pad and the main reference signal line are electrically connected by conductive material.
