    • Disclosed herein is an image display device having a plurality of light emitting diodes (LEDs), which can maintain a primary color which is desired to be expressed, and prevent an interference of other unwanted colors and a change of the primary color at the time of application of a light source of each light emitting diode. The image display device comprises: a first optical filter layer containing a violet wavelength-absorbing material having a wavelength range of from 380 nm to 450 nm such as Bi2O3 so as to prevent light having a wavelength ranging from 380 nm to 450 nm from being leaked out to an undesired region of an image display portion of the image display device; and a second optical filter layer such as a blue color filter layer so as to allow a white light to be expressed in a desired region of the image display portion.
    • 本文公开了一种具有多个发光二极管(LED)的图像显示装置,其可以保持期望表达的原色,并且防止其它不需要的颜色的干扰和原色的变化 应用每个发光二极管的光源。 图像显示装置包括:含有波长范围为380nm〜450nm的紫外线波长吸收材料的第一光学滤光层,例如Bi 2 O 3,以防止波长范围为380nm至450nm的光被泄漏 出射到图像显示装置的图像显示部分的不期望区域; 以及第二滤光器层,例如蓝色滤色器层,以便允许在图像显示部分的期望区域中表达白光。
