Abstract
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.
Claims10
A display device comprising:
- a first glass substrate;
- a second glass substrate opposing the first glass substrate, the second glass substrate including an extended area that projects in an extension direction beyond a peripheral edge of the first glass substrate, the extended area having short sides aligned with the extension direction;
- an electrooptic material layer interposed between the substrates;
- an input line disposed on the extended area of the second glass substrate;
- a data signal driver integrated circuit mechanically fixed directly to the second glass substrate via a medium at a mounting position on the extended portion, the data signal driver integrated circuit having a bump electrically connected to the input line;
- and
- a flexible circuit board substantially accommodated within the extended portion in plan view and mounted with an electronic component that overlaps the data signal driver integrated circuit in plan view, the flexible circuit board having an opposing side that at least partially opposes the data signal driver integrated circuit and a signal output terminal provided adjacent an edge of the opposing side, the signal output terminal being electrically connected to the input line at a position of the extended area between one of the short sides of the extended area and the mounting position of the data signal driver integrated circuit.
