摘要： The present invention relates to a controllable diffraction device for a light modulator device. The controllable diffraction device comprises at least two substrates, at least one electrode on each of said substrates facing each other, and liquid crystals forming at least one liquid crystal layer arranged between said electrodes on said substrates. The orientation of the liquid crystals is controllable by a voltage supplied to the electrodes. The liquid crystal layer is provided on at least one alignment layer arranged on at least one electrode on said substrates. The liquid crystals close to the alignment layer are pre-oriented by at least one pre-tilt angle relative to the alignment layer such that the resulting light diffraction in opposite spatial directions is approximately equal.
