増加して携帯用機器には不適合になる欠点があった。However, such conventional color filters have R,
The arrangement of G and B pixels (a), (b), and (c) is different,
Since all the pixels are closely arranged in a flat plate shape, the amount of light emitted from the rear light (11) is attenuated.
Since the screen appears dark, increasing the brightness of the color filter to obtain clear pixel display increases the power consumption of the light source, making it unsuitable for portable devices.
それで、本発明によればこのような欠点を解決するため
