PROBLEM TO BE SOLVED: To substantially reduce the number of connecting points and realize highly reliable signal transmission, without generating unwanted electromagnetic wave radiation even in the case of a high-density and high-definition display, or even in the case of a large-scale display. SOLUTION: Signal voltage applying elements 4a-4d and scanning voltage applying elements 7a-7d are directly mounted on a glass substrate 2a, respectively. Light-emitting means 22, 23 convert input electric signals into light signals for light signal transmission. Consequently, even in the case of high density and high definition display for which a high transmission frequency and a high rate data transmission are required, and even in the case of a large-scale screen for which a long-length transmission path is required, it is possible to eliminate in principle unnecessary radiation in the transmission line of control clock signals or display data signals to the signal voltage applying elements 4a-4d, and also substantially reduce the number of electric wiring and connecting points, and thus improve mountability and reliability. |
