Abstract
An organic EL device (2) and an sealing layer (3) are formed on a supporting substrate (1). The top surface (31) of the sealing layer is made repellent to ink. Ink is printed by an ink jet method to form a coloring layer (4). A flattening layer (8) is formed, and thereafter a sealing substrate (5) is bonded. Since the coloring layer (4) is not previously formed on the sealing substrate (5), no precise positioning for bonding the sealing substrate (5) to the supporting substrate (1) is needed. The viewing angle properties are enhanced since the distance between the organic EL device (2) and the coloring layer (4) can be small. Thus, there are provided an organic EL display of top emission type with a high production yield and excellent viewing angle properties and its production method.
