Patent ID: 7053546

Claim:
An organic electroluminescent device, comprising: a cathode; an anode; at least an organic layer between the anode and the cathode, such that when a voltage is applied to the cathode and the anode, the organic layer electroluminesces; a first substrate beneath the cathode; and a second plastic substrate above the anode, comprising: a plastic substrate; and a deposition film with a predetermined thickness formed on the plastic substrate by plasma chemical vapor deposition, the film having a formula of SiO e C a H b X c Y d Z f , wherein both e≦2 and 2−e=a+b+c+d+f are satisfied, wherein X, Y and Z are selected from the group consisting of Sc, Ti, V, Cr, Mn, Fe, Co, Ni, Cu, Zn, Pd, Ag, Pt, Au and the elements in periodic table IA, IIA, IIIA, IVA, VA, VIA and VIIA excepting H, the deposition film having transparency of at least 97%.
