Abstract
Abstract A flat matrix display panel includes a plurality of scanning electrodes, and a plurality of data electrodes formed in a matrix fashion. The data electrodes are divided into two groups, one having terminals on the upper edge of the panel, and the other having terminals on the bottom edge of the panel. A first group data driver LSI is mounted on a substrate in a face-up bonding manner, and is connected to the terminals formed on the upper edge of the panel. A second group data driver LSI, which has the same construction as the first group data driver LSI, is mounted on the same side of the substrate in a facedown bonding manner, and is connected to the terminals formed on the bottom edge of the panel.
