The present disclosure provides a liquid crystal display device including a light source unit which supplies light to a liquid crystal panel, a lower polarizing plate disposed below the liquid crystalpanel, an upper polarizing plate, a light absorption filter, and a fluorescent filter disposed above the liquid crystal panel. According to the present disclosure, when a laser pointer in a visible ray region illuminates after implementing a display image, light irradiated by the laser is absorbed by the fluorescent filter and the light absorption filter to convert the light into red, green, andblue light to be emitted, thereby improving visibility in accordance with illumination of a laser pointer. 本公开内容提供了种液晶显示装置，其包括：在其上显示图像的液晶面板，向液晶面板供应光的光源单元，设置在液晶面板下方的下偏振板，以及设置在液晶面板上方的上偏振板、光吸收滤光器和荧光滤光器。根据本公开内容，当在实现显示图像后在可见光线区域中的激光指示器发光时，由激光指示器照射的光被荧光滤光器和光吸收滤光器吸收，以将该光转换成红光、绿光和蓝光以进行发射，从而提高了关于激光指示器的照射的可视性。
