Abstract

Disclosed is a liquid crystal display device wherein a bright point can be easily converted into a black point, even in the case wherein a power supply voltage generating circuit for driving a liquid crystal panel is formed in an IC chip mounted on a board. The liquid crystal display device is provided with: a drive circuit board having the IC chip (4) mounted thereon, said IC chip having the drive circuit for driving the liquid crystal panel (2) formed therein; a facing board disposed to face the drive circuit board; the liquid crystal panel (2) having a liquid crystal layer sandwiched between the drive circuit board and the facing board; an external circuit board (6) having a stabilizing capacitive element (7) mounted thereon, said stabilizing capacitive element generating a power supply voltage in the IC chip (4); and a connecting wiring board (5) that connects the drive circuit board and the external circuit board (6) to each other. Auxiliary capacitor wiring (3) that applies an auxiliary capacitive voltage to an auxiliary capacitor disposed in the pixel region (10) of the drive circuit board, and a power supply voltage terminal (14) that supplies the power supply voltage of the IC chip (4) are directly connected on the circuit board.

Description

technical field [0001] The present invention relates to a liquid crystal display device including a liquid crystal panel on which an IC chip formed with a driving circuit is mounted on a driving circuit substrate, and particularly relates to a liquid crystal display device including a liquid crystal panel having a function of changing bright spots into black spots. Background technique [0002] A liquid crystal display device including a liquid crystal panel is the mainstream of video display terminals such as televisions and monitors of personal computers as thin and power-saving display terminals. In addition, taking advantage of the characteristics of liquid crystal panels such as thinness and light weight, they are actively used as display terminals for mobile devices and portable devices such as car navigation systems, personal digital assistants (PDAs), mobile phones, and portable game consoles. [0003] In a liquid crystal panel, generally, a predetermined voltage is ...
