At least either of the electron hole pouring layer 14a or the electron hole transportation layer 14b contains an organic material without crystallization temperature, for example, starbustamin type electron hole transportation material. Thereby, the speed of initial degradation and subsequent steady degradation is suppressed to small, and stable prolonged luminescence is obtained. COPYRIGHT: (C)2003,JPO

Abstract: PROBLEM TO BE SOLVED: To prevent the boundary of sticking from being conspicuous on a display, with which a picture is constituted while being divided, and to widen a margin on the bonding portion.
SOLUTION: On a boundary 27 of display elements 20 and 30, sub-pixels P22a and P32b are adjacent so that a pixel P23 of one unit can be configured. Since the boundary 27 of the display elements 20 and 30 passes the center of the pixel P23, the boundary is not almost conspicuous. Therefore, sufficient margins W22 and W32 for sticking the display elements 20 and 30 can be secured.
COPYRIGHT: (C)2003,JPOAbstract translation: 要解决的问题：为了防止在划分时构成图像的显示器上的粘着边界明显，并且在接合部分上加宽边缘。 解决方案：在显示元件20和30的边界27上，子像素P22a和P32b相邻，使得可以配置一个单元的像素P23。 由于显示元件20和30的边界27通过像素P23的中心，所以边界几乎不显眼。 因此，可以确保用于粘贴显示元件20和30的足够的边缘W22和W32。
