Abstract

The present invention relates to semiconductor substrates and electronic devices. The semiconductor substrate includes: a thin film transistor including an organic semiconductor layer; and a light absorbing light transmitting layer disposed in a path that guides external light to the organic semiconductor layer. The light-absorbing light-transmitting layer absorbs light in a wavelength range including at least a part of the light-absorbing wavelength range of the organic semiconductor layer, and allows transmission of light in the remaining other wavelength ranges. The electronic device includes a light source, light generated from the light source as the external light, and the above-mentioned thin film transistor. The semiconductor substrate and the electronic device of the present invention can secure the electrical characteristics of the organic semiconductor layer.

Description

[0001] Cross References to Related Applications [0002] This application contains subject matter related to that disclosed in Japanese Priority Patent Application JP 2011-183985 filed in Japan Patent Office on Aug. 25, 2011, the entire content of which is hereby incorporated by reference. technical field [0003] The present invention relates to a semiconductor substrate provided with a thin film transistor including an organic semiconductor layer and an electronic device using the semiconductor substrate. Background technique [0004] In recent years, various electronic devices use a thin film transistor (TFT) as a switching element and the like, and the TFT is mounted on the electronic device as a part of a semiconductor substrate. Regarding TFTs, an organic TFT that uses an organic semiconductor material to form a semiconductor layer (channel layer) has recently been considered as a promising alternative to an inorganic TFT that uses an inorganic semiconductor material t...
