摘要

A CCM substrate (1) includes as a light-emitting layer on a substrate (11) a red conversion layer (142), a green conversion layer (152), and a light scattering layer (162); a bank (13) which stands on the substrate (11), and partitions the light-emitting layer; and a light-transmission suppressing layer (10) which is formed on at least a portion of a side surface (13a) of the bank (13) which is a surface facing the light-emitting layer, and suppresses light transmission between the light-emitting layers (the red conversion layer (142), the green conversion layer (152), and the light scattering layer (162)) with the bank (13) interposed therebetween by causing the light to be reflected or scattered, in which the light-transmission suppressing layer (10) is comprising metal or metal salt, and the bank (13) has a group, an ion, or a molecule for immobilizing the metal or metal ion.
