In the present invention, a partition wall having a matrix shape is formed on anode electrodes so as to divide them further into dots of a small region, which are surrounded by the partition wall. With this structure, if a dark spot which is a non-light emitting region, is created in one dot, the growth of the spot can be stopped by the partition wall. Therefore, good display property can be maintained for a long time.
