A display device includes a display panel having an electrooptic material provided between a pair of substrates opposed to each other. The display panel has a driver integrated circuit mounted on an extended area in which an edge of one of the substrates extends further than an edge of the other substrate. The extended area is provided in at least a margin of the display panel. A control circuit board is provided above the driver integrated circuit almost within the extended area. The control circuit board is connected to the input terminal portion of the driver integrated circuit.

Display device and electronic apparatus

A composite flexible wiring board comprises a first flexible wiring board and a second flexible wiring board on which a surface-mounted part is provided. The second flexible wiring board is disposed on the first flexible wiring board in its predetermined area. The first flexible wiring board and the second flexible wiring board are electrically connected to each other through an interlayer contact portion provided in a predetermined position. The first flexible wiring board has an input terminal region and an output terminal region with a power IC chip mounted on the first flexible wiring board.

Composite flexible wiring board, method of manufacturing the same, electro-optical device, and electronic equipment

A first driver IC is mounted in the area which includes one side of the panel substrate on an electro-optical panel, and the edge portion of the film base material on which a second driver IC is mounted is bonded to the vicinity of the one side of the above-mentioned panel substrate. Also, driver-controlling electronic components which each provides control signals to the first and second driver ICs are mounted on the same surface as the second driver IC in the film base material.

Flexible substrate, electro-optical device and electronic device

Connection terminals connected to a scanning driver IC chip are arranged on a short side of a wiring connection area A of a second substrate in a liquid crystal display panel , and the connection terminals and connection terminals arranged on a long side of a wiring connection area A of a first substrate are connected from the same direction with a single flexible printed wiring board . For this reason, convenience of the flexible printed wiring board can be improved. In addition, it is possible to reduce the projection size of the wiring connection area of the first substrate , and the ratio of the display area in the whole liquid crystal panel can be increased.
