Zusammenfassung:	本发明的液晶显示部件中的背光包括一个透明基底和一设置在该透明基底上的有机电致发光元件。该背光将从该有机电致发光元件发出的光线从该透明基底的光射出表面发出。在该光射出表面上形成有多个凹坑。在每相邻的凹坑对之间的一部分光射出表面包括一个垂直于该透明基底的厚度方向的平面。该背光能够使从有机电致发光元件发出的光线有效的发出。 A backlight in a liquid crystal display unit according to the present invention has a transparent substrate and an organic electroluminescent element provided on the transparent substrate. The backlight emits light emitted from the organic electroluminescent element from a light exit surface of the transparent substrate. A plurality of recesses are formed in the light exit surface. A part of the light exit surface between each adjacent pair of the recesses includes a plane that is perpendicular to the thickness direction of the transparent substrate. The backlight permits light emitted from the organic electroluminescent element to be efficiently emitted.
