Abstract

Жидкокристаллический дисплей (LCD) содержит первую пленку из триацетатцеллюлозы (ТАС), первую оптическую одноосную фазокомпенсационную пленку, ячейку LC, вторую оптическую одноосную фазокомпенсационную пленку и вторую пленку из ТАС от поверхности, на которую падает свет, до поверхности, которая отражает свет. Первая оптическая одноосная фазокомпенсационная пленка применима для обеспечения первой величины компенсации и второй величины компенсации путем регулировки толщины и путем регулировки первого показателя преломления, второго показателя преломления и третьего показателя преломления. Вторая оптическая одноосная фазокомпенсационная пленка применима для обеспечения третьей величины компенсации путем регулировки толщины и путем регулировки четвертого показателя преломления, пятого показателя преломления и шестого показателя преломления. Рассеяние светового потока является управляемым согласно первой величине компенсации, второй величине компенсации и третьей величине компенсации в LCD.
