Abstract
Distortion of an LED array head is eliminated by correcting an electrode pitch misalignment between an LED array substrate and a driver substrate to be caused by thermal expansion or contraction during thermal pressure bonding of a flexible cable. A tear preventing hole is formed in each area between adjacent four-divided areas of the flexible cable. When positions of the flexible cable and driver substrate are to be aligned, a pitch shift adjusting slit line is cut in order to correct the position misalignment to be caused by thermal expansion or contraction generated when the flexible cable is thermal-pressure bonded to the LED substrate. The pitch shift adjusting slit line is formed in the connection area between adjacent four-divided areas.
