The present invention relates to variable optical transmission windows and window panels (VLTP) which are used for architectural applications such as building entryway systems and windows. The optical transmission of the VLTPs is reversibly changed by applying an electrical voltage. This disclosure includes combination of more than one VLTP in a single window which darken to different colors. This disclosure is directed to the use and powering of such panels in door and windows. The doors and windows having these VLTPs may also have other electronic devices which provide added user functionality.

In a liquid crystal device, an intermediate refractive index film including a silicon nitride film, a silicon oxynitride film, or an aluminum oxide film is provided between an oriented film formed of a diagonally vapor-deposited film of silicon oxide and an electrode containing ITO. Thus, because there are no interfaces having a large refractive index difference between the oriented film and the electrode, reflection between the oriented film and the electrode can be suppressed. A high density silicon oxide film is formed between the intermediate refractive index film and the oriented film. The high density silicon oxide film is formed by an atomic deposition method, thus is appropriately formed inside a contact hole.

A method for influencing light propagation directions of a light-emitting surface emitting light of a first wavelength range in a first direction and light of a second and wavelength range in a second direction. The wavelength ranges have a wavelength-dependent spectral radiance and differ in a peak wavelength. A switchable color converter is arranged in front of the light-emitting surface. The method includes the steps of a) deactivating the color converter for a first mode so that the second-wavelength range is transmitted and the first-wavelength range is absorbed, such that light from the light-emitting surface is only perceptible from the second direction, or b) activating the color converter for a second mode so that light of the first-wavelength range is converted into light of the second-wavelength range and light of the second-wavelength range is transmitted, such that light from the light-emitting surface is perceptible from both directions.
