Abstract

A plurality of clear luminous colors are obtained without having color interference by reflected light by other constituent materials. The constitution includes a first light-permeable electrode layer formed at the back side of a transparent substrate, a first luminous material layer containing a first luminous material, an intermediate light-permeable electrode layer, a second luminous material layer containing a second luminous material, a back electrode, and at least two elements of (i) a first color material contained in the first luminous material layer, (ii) a second color material contained in the second luminous material layer, and (iii) luminous color converting layer containing a third color material, disposed between the first luminous material layer and second luminous material layer, and a color coat layer containing a fourth color material, disposed at the front surface side of the transparent substrate. The color material closer to the back electrode of the at least two elements has the color of longer wavelength than the remoter color material.

Description

technical field [0001] The present invention relates to electroluminescent lamps (hereinafter referred to as EL lamps), in particular to dispersion-type EL lamps emitting polychromatic light. Background technique [0002] For the traditional multi-color light-emitting dispersive EL lamp, take the two-color light-emitting dispersive EL lamp as an example, use Figure 5-Figure 7 Be explained. [0003] In addition, in each figure, the dimension of the thickness direction is exaggerated in order to understand a structure easily. [0004] Figure 5 A perspective view of the appearance of a conventional two-color emission dispersion type EL lamp is shown. Image 6 shown along the Figure 5 The cross-sectional view of line 71-72 after the up-down and left-right inversion. Figure 7 shown along the Figure 5 The cross-sectional view of the 81-82 line after the up-down and left-right inversion. [0005] exist Figure 5 , Image 6 and Figure 7 Among them, the traditional two...
