Abstract
A thin-film semiconductor device includes a temperature sensor formed of a thin-film semiconductor and sensing a temperature as current, and a current-voltage converter formed of a thin-film semiconductor and having temperature dependence in which its current-voltage characteristic is different from that of the temperature sensor. A temperature sensed by the temperature sensor is converted to a voltage by the current-voltage converter.
Claims1
