IMAGE DISPLAY DEVICE WITH PLURAL LIGHT EMITTING DIODES |
摘要 |
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. |
