Abstract

Se proporciona un dispositivo de pantalla de cristal líquido, que incluye, en este orden, una fuente de luz, una capa de difusión óptica, y un panel de cristal líquido que tiene placas de polarización dispuestas en ambas superficies de una celda de cristal líquido, en donde la superficie de la capa de difusión óptica en el lado del panel de cristal líquido tiene una forma fina periódica, y una superficie superior de la placa de polarización dispuesta en el lado visible del panel de cristal líquido tiene una capa anti-reflejo que tiene una forma irregular fina aleatoria y que tiene un grado de claridad de transmisión de no más de 15%. Mientras tiene un alto brillo con menos energía eléctrica según comparado con la técnica anterior, el dispositivo de pantalla de cristal líquido no genera una franja de interferencia.
