    • A multiple wavelength light emitting device is provided wherewith the resonance strength and directivity between colors can be easily adjusted for balance. This light emitting device comprises a light emission means 4 for emitting light containing wavelength components to be output, and a semi-reflecting layer group 2 wherein semi-reflecting layers 2R, 2G, and 2B that transmit some light having specific wavelengths emitted from the light emission means and reflect the remainder are stacked up in order in the direction of light advance in association with wavelengths of light to be output. Light emission regions AR, AG, and AB are determined in association with the wavelengths of light to be output. The configuration is such that, in the light emission regions, the distances LR, LG and LB between a reflecting surface for fight from the light emission means side of the semi-reflecting layers 2R, 2G, and 2B that reflect light output from those light emission regions and a point existing in an interval from the end of the light emitting layer on the semi-reflecting layer group side to the reflecting layer are adjusted so as to have an optical path length at which that light resonates.
    • 提供了多波长发光器件,其中可以容易地调节颜色之间的共振强度和方向性。 该发光装置包括用于发射包含要输出的波长分量的光的发光装置4和半反射层组2,其中透射从光发射的具有特定波长的一些光的半反射层2R,2G和2B 发射装置和反射余下部分依次输出的光的波长与光的前进方向重叠。 与要输出的光的波长相关联地确定发光区域AR,AG和AB。 该配置使得在发光区域中,从反射从这些光输出的光的半反射层2R,2G和2B的发光装置侧的反射面之间的距离LR,LG和LB 发光区域和从半反射层组侧的发光层的端部到反射层的间隔中存在的点被调节为具有该光共振的光程长度。
