Abstract
The invention provides a circuit substrate including an electrostatic-breakdown-protection circuit efficient for an EL display panel or the like. A substrate includes a common electrode formed on the perimeter of the substrate, multiple terminals formed on the substrate, one or more first resistances formed between adjacent terminals, and one or more second resistances formed between the terminals and the common electrode. The terminal is connected to both the first resistance and the second resistance. The first resistance has a resistance value greater than the second resistance.
