Abstract: Ribs for defining pixel cells are formed in the shape of a lattice, and sustain electrodes and scan electrodes are disposed near the ribs. The electrodes are spaced apart in each pixel cell, and the sustain electrode and the scan electrode are each cut away between pixel cells arranged in the row direction to provide each pixel cell with individually separated electrodes. In addition, between pixel cells adjacent to each other in the row direction, the sustain electrodes and the scan electrodes are connected to each other by means of a sustain-side bus electrode and a scan-side bus electrode, respectively. This makes it possible to provide a high luminous efficiency. Furthermore, each pixel cell is provided with a wide distance between the electrodes and thereby with a large effective opening portion. Thus, this provides only a small amount of reduction in intensity when the electrodes are spaced apart between the pixel cells arranged in the row direction in order to increase the luminous efficiency. The sustain electrodes or the scan electrodes can be connected to each other or shared between pixel cells adjacent to each other in the column direction and thus the effective opening portion can be made larger, thereby making it possible to provide a further increased intensity and luminous efficiency.

Abstract translation: 用于限定像素单元的肋形成为格子形状，并且维持电极和扫描电极设置在肋附近。 电极在每个像素单元中间隔开，并且维持电极和扫描电极各自在排列在行方向上的像素单元之间被切除，以为每个像素单元提供单独分离的电极。 此外，在行方向上彼此相邻的像素单元之间，维持电极和扫描电极分别通过维持侧总线电极和扫描侧总线电极相互连接。 这使得可以提供高的发光效率。 此外，每个像素单元在电极之间设置有较大的距离，从而具有大的有效开口部分。 因此，为了提高发光效率，当在行方向上排列的像素单元之间间隔开电极时，这仅提供少量的强度降低。 维持电极或扫描电极可以彼此连接或者在列方向上彼此相邻的像素单元之间共享，从而可以使有效开口部分更大，从而可以进一步提高强度和发光效率 。
