Abstract

PROBLEM TO BE SOLVED: To disperse with a two-layer board and to enhance reliability with low cost by forming an output terminal having wirings connected to an LSI ship at one side, and forming input terminals having wrings connected to the chip on the same surface at two sides crossing the one side. SOLUTION: A flexible circuit board (COF) 4 has (a) to (h) of input terminals 2, disposed in parallel with each other and perpendicular to an output terminal 1. The reason for the (a) to (h) of the terminals 2 being disposed on the same line is due to the respective COF 4 being connected in cascade. When they are not connected in cascade, the input terminals can be concentrated in either the right of left direction.
