    • A white electroluminescence element (1) comprising an anode (2), a blue light emitting layer (5) containing a host material and a blue dopant, yellow through red light emitting layer (6) containing a host material identical to that of the blue light emitting layer (5) and a yellow through red dopant, and a cathode (8), formed sequentially in layers, wherein the light emitting layer is composed of the blue light emitting layer (5) and the yellow through red light emitting layer (6). In a type where the light emitting layer is divided into two, trend of color shift toward red can be canceled by employing the blue light emitting layer (5) on the anode (2) side where the light emitting region of the emitting layer has a trend to shift. Since the yellow through red light emitting layer (6) can be formed thick, variation of chromaticity can be suppressed.
    • 包含阳极(2),含有主体材料的蓝色发光层(5)和蓝色掺杂剂的白色电致发光元件(1),包含与蓝色相同的主体材料的黄色至红色发光层(6) 发光层(5)和黄色通过红色掺杂剂和阴极(8),其中发光层由蓝色发光层(5)和黄色至红色发光层( 6)。 在发光层被分成两个的类型中,通过在发光层的发光区域具有阳极(2)侧的阳极(2)侧采用蓝色发光层(5),可以抵消向红色的偏移趋势 趋势转移。 由于黄色贯通红色发光层(6)可以形成得较厚,所以可以抑制色度的变化。
