Abstract
An active matrix board comprising: an electrically insulating transparent substrate; a pixel electrode disposed in two dimensions on the substrate for each pixel; a scanning electrode arranged in common to the pixel electrodes disposed along a predetermined direction; and a switching element disposed between each of the pixel electrodes and the scanning electrode. The switching element is constituted from a thin film two-terminal element which is composed of a first conductor, a second conductor, and a hard carbon film. The hard carbon film is disposed between the first and second conductors. The element has a standard deviation of current distribution in a surface of the substrate when applied with a predetermined voltage which deviation is less than 35% of the current average.
