In a liquid crystal display device with a drive circuit board connected to the peripheral portion of a liquid crystal display panel, the circuit board is disposed behind the liquid crystal display panel and also the circuit board is connected with the liquid crystal display panel by means of a connecting member in film form, whereby the liquid crystal display device is miniaturized and efficiency of the assembly work is improved. Further, the circuit board is made up of plural drive circuit modules of the same type whereby the efficiency in the assembly and inspection process is still improved.

DETAILED DESCRIPTION The present invention was made to overcome the above mentioned problems.
Accordingly, an object of the present invention is to provide a liquid crystal display device in which operating efficiency in the assembly work and the yield rate of the drive circuit boards are improved and the miniaturization of the device can be achieved.
In a liquid crystal display device with a circuit board including drive ICs and drive circuits connected at the peripheral portion of a liquid crystal display panel, the liquid crystal display device according to the present invention has the circuit board disposed behind the liquid crystal display panel and comprises a connecting member in film form for electrically connecting the panel with the circuit board.
According to the present invention, the circuit board connected to the liquid crystal display panel does not protrude from the periphery of the panel, thereby enabling miniaturization of the liquid crystal display device.
Another object of the present invention is to provide an active matrix liquid crystal display device, wherein, in connecting opposing drive circuit modules on each of the source side and the gate side to the liquid crystal display panel, drive circuit modules composed of ICs of the same type and circuit boards of the same type are used, whereby the assembly process is simplified, the yield rate in the assembly work is improved, and further, miniaturization of the device is achieved.
