PURPOSE:To make TFT free from AC noise possible by arranging thin film polarizers separating them at a space of light wavelength and setting the direction of polarization of the polarizers to make the state of extinction with polarizers provided on a glass substrate facing the matrix substrate of a display unit. CONSTITUTION:Metallic thin film polarizers 18 are provided on the surface of a protective film 16 and the metallic thin film polarizers 18 are arranged in the direction X along the direction of current between source drain electrodes 14, 15 at light wavelength space (d) and separate in the direction Y which is right angles to the direction X. Actual value of (d) is about 5,000Angstrom , and separated forming of metallic thin film polarizers of this spacing can be made by using photolithography by electron beam or X-ray. The direction of polarization of metallic thin film polarizers 18 is arranged to make 90 deg. to the direction of polarizers provided on a glass substrate facing the matrix substrate (transparent glass substrate 17) of a display unit on which the thin film TFT are mounted, that is, to make the state of extinction. |
