    • An optical filter for compensating for color shift is provided in front of a display panel of a display device. The optical filter includes a background layer and a green wavelength absorption pattern provided with a predetermined thickness on the background layer. The green wavelength absorption pattern absorbs a green wavelength of light. The green wavelength absorption pattern contains a material that absorbs a green wavelength of light in the range of 510 nm to 560 nm, and can also contain a white light absorbing material. A green's complementary color absorbing part absorbs a wavelength of light complementary to green, and contains at least one of a material absorbing a blue wavelength of light in the range of 440 nm to 480 nm and a material absorbing a red wavelength of light in the range of 600 nm to 650 nm. A first thick-film layer, a first thin-film layer, and a second thick-film layer are stacked over one another in the order named.
    • 在显示装置的显示面板的前面设置用于补偿色移的光学滤波器。 滤光器包括在背景层上设置有预定厚度的背景层和绿色波长吸收图案。 绿色波长吸收图案吸收绿色的波长的光。 绿色波长吸收图案包含吸收510nm至560nm范围内的光的绿色波长的材料,并且还可以含有白色光吸收材料。 绿色的补色吸收部分吸收与绿色互补的光的波长,并且包含吸收在440nm至480nm范围内的蓝色波长的光的材料中的至少一种和吸收范围内的红色波长的光的材料中的至少一种 为600nm至650nm。 第一厚膜层,第一薄膜层和第二厚膜层以所述顺序彼此堆叠。
