Abstract

PURPOSE:To enable to connect two pieces of the LSI elements constituting an LSI element for liquid crystal drive without making a wiring cross on the liquid crystal panel by a method wherein wiring free distribution exclusive terminals are provided between the same signal terminals in the LSI element for liquid crystal drive with the same signal terminals provided at two placed in a mirror symmetrical state. CONSTITUTION:LSI elements 11 and 12 consisting of the same type are made the same signal terminals 13-15 thereof dispose in a mirror symmetrical state and solder bumps for connection are formed to the signal terminals 13-15. When a signal (c) different from a signal (b) to be applied to the terminal 14 of the LSI element 11 is applied to the terminal 14 of the LSI element 12, the signal (c) is once connected to a wiring free distribution exclusive terminal 16 on the input side of the LSI element 11 and when a wiring free distribution exclusive terminal 16 on the output side of the LSI element 11 is connected to the terminal 14 on the input side of the LSI element 12, the connection between the LSI elements 11 and 12 can be performed without making a wiring cross on the liquid crystal panel. As the wiring free distribution exclusive terminals are provided between the same signal terminals of the LSI elements in such a way, the mutually different signals can be applied to the same signal terminals of two pieces of the LSI elements without making a wiring cross on the liquid crystal panel.
