Organic EL panel having partitions separating pixels
View Patent ↗For an organic EL panel, whereon partitions are used to separate pixels, transparent electrodes, a charge generation layer and a charge transfer layer are formed in the named order on a substrate. Then, when the charge transfer layer is electrified and the charge generation layer is selectively exposed, an electrostatic latent image having a predetermined pattern is formed on the charge transfer layer. Subsequently, to form the partitions, the electrostatic latent image is developed by using a developing agent and the developing agent is fixed. Following this, emission layers and opposing electrodes to the transparent electrodes are positioned between the thus obtained partitions.
1. An organic EL panel comprising:
a transparent substrate;
a first electrode, composed of a transparent material, that is formed on said transparent substrate;
a charge generation layer covering said first electrode;
a charge transfer layer formed thereon; partitions formed on said charge transfer layer by using a developing agent pattern having
a predetermined shape; and
an emission layer and a second electrode formed between said partitions.
2. The organic EL panel according to claim 1 , wherein the width of each of said partitions is 10 to 40 μm.
3. The organic EL panel according to claim 1 , wherein said partitions are black.
4. The EL panel according to claim 1 , wherein said charged transfer layer is made of organic material.
