Organic EL display panel and method of manufacturing the same
View Patent ↗An organic EL display panel is provided which includes: a substrate which includes a plurality of luminescent regions which are arranged side by side in a specific direction and run in parallel to one another; a bank formed over the substrate, the bank defining a plurality of coating regions in each of the luminescent regions, the coating regions being aligned in a row along the long axis of the luminescent region; and a pixel electrode provided in each of the coating regions, the pixel electrode having a long axis which is in parallel with the long axis of the luminescent region, wherein, in each of the luminescent regions, the coating region positioned at a lengthwise end of the luminescent region is larger in size than the coating region positioned at a lengthwise center of the luminescent region.
1. An organic EL display panel comprising:
a substrate which includes a plurality of luminescent regions which are arranged side by side in a specific direction and run in parallel to one another;
a bank formed over the substrate, the bank defining a plurality of coating regions in each of the luminescent regions, the coating regions being aligned in a row along the long axis of the luminescent region; and
a pixel electrode provided in each of the coating regions, the pixel electrode having a long axis which is in parallel with the long axis of the luminescent region, wherein
in each of the luminescent regions, the coating region positioned at a lengthwise end of the luminescent region is larger in size than the coating region positioned at a lengthwise center of the luminescent region, and
in each of the luminescent regions, the number of the pixel electrodes in the coating region positioned at the lengthwise end of the luminescent region outnumbers the number of the pixel electrodes in the coating region positioned at the lengthwise center of the luminescent region.
2. The organic EL display panel according to claim 1 , wherein the coating regions monotonically decrease in size from the lengthwise ends to the lengthwise center of the luminescent regions.
3. The organic EL display panel according to claim 1 , wherein the average area of the coating regions in each of the luminescent regions positioned at both edges in the specific direction of the panel is larger than the average area of the coating regions in the luminescent region positioned at a center in the specific direction of the panel.
4. The organic EL display panel according to claim 3 , wherein the coating region positioned at the lengthwise center of the luminescent region positioned at the edge in the specific direction of the panel is larger than the coating region positioned at the lengthwise center of the luminescent region positioned at the center in the specific direction of the panel.
