Liquid crystal display device and video projector incorporating same with particular driving circuit connection scheme

A liquid crystal display device comprising:

• a substrate having a plurality of recesses or openings formed therein,
• a plurality of liquid crystal display panels respectively partially inserted in said plurality of recesses or openings thereby to be mounted on said substrate, each of said display panels having a liquid crystal display region having a plurality of terminal electrodes,
• a drive circuit provided on said substrate for generating drive signals for driving said liquid crystal display panels,
• a plurality of first wiring leads formed on said substrate for electrically connecting said plurality of liquid crystal display panels and said drive circuit, each of said first wiring leads being connected at one end thereof to said drive circuit, and
• a plurality of second wiring leads formed on said substrate for electrically connecting adjacent two of said plurality of liquid crystal panels to each other,
• the other end of each of said plurality of first wiring leads and a corresponding one of said plurality of terminal electrodes being connected to each other through interposed conductive bump and conductive joint layer which are connected with each other, and each end of each of said plurality of second wiring leads and a corresponding one of said plurality of terminal electrodes being connected to each other through interposed conductive bump and conductive joint layer which are connected with each other.
