Abstract:
Provided is a substrate for an organic electroluminescence device having the following characteristics: occurrence of withdrawal of an organic electroluminescence material can be suppressed, and, even when the withdrawal occurs owing to, for example, impurities on the substrate, such a problem that stop of film formation for one entire line can be suppressed, and hence yields can be improved. The substrate for an organic electroluminescence device including at least pixel electrodes and stripe-shaped banks has projections between the stripe-shaped banks.
