• Subjects: DEVICES OR ARRANGEMENTS, THE OPTICAL OPERATION OF WHICH ISMODIFIED BY CHANGING THE OPTICAL PROPERTIES OF THE MEDIUM OF THEDEVICES OR ARRANGEMENTS FOR THE CONTROL OF THE INTENSITY,COLOUR, PHASE, POLARISATION OR DIRECTION OF LIGHT, e.g.SWITCHING, GATING, MODULATING OR DEMODULATING; FREQUENCY-CHANGING; NON-LINEAR OPTICS; OPTICAL ANALOGUE/DIGITAL CONVERTERS; OPTICAL LOGIC ELEMENTS; OPTICS; PHYSICS; TECHNIQUES OR PROCEDURES FOR THE OPERATION THEREOF

A display device comprises: a liquid crystal panel; first and second polarizing plates respectively coupled to the front and rear of the liquid crystal panel; and a light absorption layer on which light which has passed through the first polarizing plate, the liquid crystal panel, and the second polarizing plate in order is incident, and which is disposed on the front surface of the second polarizing plate positioned in front of the liquid crystal panel. The light absorption layer comprises: a first resin layer; a second resin layer on which light which has passed through the first resin layer is incident, and which is formed to have a higher refractive index than the first resin layer; and light absorption parts disposed in the first rein layer and configured to absorb some of the light passing through the light absorption layer. With this configuration, the field of view of the display device can be improved. L'invention concerne un dispositif d'affichage comprenant : un panneau à cristaux liquides ; des première et seconde plaques de polarisation respectivement couplées à l'avant et à l'arrière du panneau à cristaux liquides ; et une couche d'absorption de lumière sur laquelle la lumière qui a traversé la première plaque de polarisation, le panneau à cristaux liquides et la seconde plaque de polarisation dans cet ordre est incidente, et qui est disposée sur la surface avant de la seconde plaque de polarisation positionnée devant le panneau à cristaux liquides. La couche d'absorption de lumière comprend : une première couche de résine ; une seconde couche de résine sur laquelle la lumière qui a traversé la première couche de résine est incidente et qui est formée pour avoir un indice de réfraction supérieur à celui de la première couche de résine ; et des parties d'absorption de lumière disposées dans la première couche de résine et conçues pour absorber une partie de la lumière traversant la couche d'absorption de lumière. Avec cette configuration, le champ de vision du dispositif d'affichage peut être amélioré. 디스플레이 장치는 액정패널과, 액정패널의 전후방에 각각 결합되는 제 1, 2 편광판과, 제 1 편광판, 상기 액정패널, 상기 제 2 편광판을 순차적으로 지난 광이 입사되며, 상기 액정패널 전방에 위치하는 상기 제 2 편광판의 전면에 배치되는 광흡수층을 포함한다. 광흡수층은 제 1 레진층과, 상기 제 1 레진층을 지난 광이 입사되며, 상기 제 1 레진층보다 굴절율이 높게 형성되는 제 2 레진층과, 상기 제 1 레진층에 배치되어 상기 광흡수층을 지나는 광의 일부가 흡수되도록 구성되는 광흡수부들을 포함한다. 이러한 구성을 통해 디스플레이 장치의 시야각을 개선할 수 있다.
