Abstract

본 발명은 시야 범위를 넓게 할수 있는 액정표시 소자에 관한 것으로, 종래에는 사용자는 액정표시 소자 표면 수직을 중심으로 각 좌,우 방향 25°이상에서 상편광판을 통과한 빛을 볼 수 없었으나, 본 발명에서는 상편광판(2)위에 구면경렌즈(7)를 형성하여 상편광판(2)의 빛을 굴절하므로써 사용자의 시야 범위를 넓게 하므로 상기 결점을 개선 시킬수 있는 것이다.The present invention relates to a liquid crystal display device capable of widening the field of view. In the related art, a user has not been able to see the light passing through the upper polarizing plate at 25 ° or more in the left and right directions, centered on the surface of the liquid crystal display device. In the present invention, by forming a spherical mirror lens 7 on the upper polarizing plate 2 to refract the light of the upper polarizing plate 2, the user's field of view can be widened, thereby improving the above-mentioned shortcomings.
