Abstract: A liquid crystal display device having a non-rectangular display panel includes an active area which is defined by a peripheral shield layer. A plurality of pixels are formed in the active area in a matrix, and each pixel includes a plurality of sub-pixels to display colors different from each other. A part of the sub-pixels of peripheral pixels located in a peripheral region of the active area is covered with a peripheral shield layer. Shield elements are arranged in the sub-pixels which are not covered with the peripheral shield layer so that an effective display area of each of the sub-pixels of the peripheral pixel is substantially equal.

Abstract: A liquid crystal display device having a non-rectangular display panel includes an active area which is defined by a peripheral shield layer. A plurality of pixels are formed in the active area in a matrix and typically each pixel includes a plurality of sub-pixels to display respective different colors.

A part of the first pixel located in a peripheral region of the active area is covered with the peripheral shield layer. The thickness of the color filter layer arranged in the first pixel where the peripheral shield layer overlaps with the first pixel is smaller than that of a same color filter arranged in the second pixel having a larger effective display area than that of the first pixel area.

Abstract: A liquid crystal display device includes an array substrate having a power supply line for supplying a power voltage to a counter electrode of a counter substrate. The power supply line connects a power pad arranged at a corner of the array substrate to a common line which is arranged between an active area and a seal portion, crossing the seal portion provided at a peripheral portion of the array substrate so as to surround the active area. The array substrate further includes at least two block elements with a convex shape for blocking the flowing out of the sealing element to the active area. The block elements are arranged so as to cross the power supply line and face the power supply pad. A gap between the block elements and the counter substrate is smaller than a gap between the slit formed by the adjacent block elements and the counter substrate.

Abstract: In a semiconductor integrated circuit device of a liquid crystal display drive controller, the present invention is intended to suppress an increase in the number of output terminals for interface control signals for control of parallel interface to a sub liquid crystal display controller. A host interface circuit comprises a first serial interface circuit for serial data input and output in a differential manner, a parallel interface circuit, and other interface circuits. When the first serial interface circuit is selected for use as the host interface, the host interface circuit outputs in parallel predetermined information input via the first serial interface circuit from the parallel interface circuit to outside and generates interface control signals for the parallel output. External terminals for host interface assigned to the other interface circuits are used for double duty to output the interface control signals.

Abstract: A liquid crystal display device includes a plurality of pixels arranged near intersections between signal lines and scan lines in a matrix to form a display area. The scan lines and signal lines extend in a row and a column directions of the pixels in the display area. A first conductive layer is arranged on an insulating substrate. A second conductive layer is arranged on the first conductive layer through an insulating layer. The second conductive layer is electrically connected to the signal line. The first conductive layer includes an opposite region opposite to the second conductive layer and is arranged to surround the display area. The opposite region includes a cut out portion in which a disconnected scan line is repaired by irradiating the cut out portion with laser.

Abstract: The present invention provides a noncontact interface technique capable of performing communication operation without stopping an internal operation even when a clock signal cannot be extracted from a carrier wave. In a semiconductor device that receives a modulated carrier wave from an antenna, generates an internal clock signal on the basis of a clock signal extracted from the received carrier wave, and performs operation synchronously with the internal clock signal, a PLL circuit that receives the extracted clock signal and generates the internal clock signal is provided with a voltage control oscillation function. In the case where the clock signal extracted from the carrier wave is discretely interrupted, the function makes the internal clock signal maintained at a frequency immediately before the interruption. With the configuration, even when the clock signal extracted from the carrier wave is interrupted, internal data processes such as decoding and bus interfacing can be continued.

A power supply circuit is provided between an instruction register of a liquid crystal driver and a powersupply unit. The power supply unit is not directly supplied with a setting value registered to the instruction register from a microprocessor unit. The microprocessor unit writes setting values to the instruction register without need for the time axis. To turn on the power, the time is measured inside the power supply sequencer. Set values are sequentially input to the power supply unit. The instruction register should be also capable of registering an input timing.
