Abstract

An electroluminescent matrix display device which displays images with uniform brightness on its panel having connecting terminals for both scanning and data electrodes formed on one side of the panel is disclosed. Scanning electrodes requiring larger current than data electrodes are formed vertically on the panel so that they can be connected directly to the terminals formed on the bottom side of the panel, and data electrodes are formed horizontally to be connected to the terminals at the bottom side through wiring leads. Since the wiring leads have different lengths and resistances from one another, the resistances are compensated or adjusted by changing widths of the wiring leads or adding compensating resistors thereto so that the wiring resistances become uniform or differences thereof are reduced. Running directions of the scanning and data electrodes may be exchanged. In this case, wiring resistance differences for the scanning electrodes are eliminated or reduced in a similar manner as done for the data electrodes. In both cases, uniformity of image brightness is much improved.
