In this study, We have investigated degradation effects of blue organic electroluminescence devices that was consisted of TPD(N,N'-dyphenyl-N-N\`-bis(3-methyphenyl) as hole transport layer and Butyl-PBD (2- (4-Biphenylyl)-5-(4-tert-butylphenyl)-1,3,4-oxadiazole)-as emission layer and electron transport layer. We have studied characteristics of brightness and current density about blue OEL that was degradated layer. Two kinds of samples that were fabricated each continuous and non-continuous method was used.

In this study, the matrix Organic Electroluminescence (OEL) device, that was consisted of R,G,B pixels. We fabricated OEL devices by side by side methode and, used organic material Alq3 as green, DCM as red and Butyl PBD as blue ETL. We investigated the characteristic of brightness and current density for matrix OEL device. As the results, each color devices has minimum about $100cd/m^{2}$ brightness and maximum luminescence was $2500cd/m^2$ in green OEL device.

The Organic Electroluminescence (OEL) device, that was consisted of ALq3(8-hydroxyquinoline aluminum) and TPD(N,N'-diphenyl-N,N'-bis(3-methylphenyl)-1,1'-biphenyl-4,4'-diamine), has been used. We investigated characteristics of brightness and current density about OEL that was oxidated each layers. We used two samples that were fabricated each continuous and non-continuous method. Emission was observed above 10mA/$\textrm{cm}^2$ and luminance was measured to be 1530cd/$\textrm{cm}^2$ at a current density of 100mA/$\textrm{cm}^2$. A luminance of over 2600cd/$\textrm{cm}^2$ was also observed after the final fabrication process.
