Patent ID: 7928651

Claim:
An organic electro luminescence device comprising: first and second substrates arranged to face each other; a thin film transistor (TFT) formed on a TFT region of the first substrate in each sub-pixel including an emission region, the TFT region and a storage capacitor region; a first electrode formed on the emission region of each pixel of the first substrate and connected to the TFT, wherein the first electrode is formed on an array element which is formed on the first substrate; an organic electro luminescent layer on the emission region of each pixel; a second electrode formed on at least two more pixels; a black matrix disposed below the first electrode and directly on the array element of the emission region of each pixel; and a passivation layer disposed between the first electrode and the black matrix and corresponding to the first electrode and the black matrix, wherein a portion of the black matrix is disposed between a drain electrode of the TFT and a portion of the first electrode, and the entire portion of the black matrix is overlapped with the first electrode, wherein the second electrode is formed of Al, Mg or Ca which is a metal having a low work function, wherein the second electrode is formed of one of ITO and IZO, wherein the second electrode is formed in a dual layer including Al of 10 Å and ITO of about 1000 Å, and wherein the passivation layer includes an inorganic material for preventing unintended chemical reactions between boundaries of the first electrode and the black matrix, and the passivation layer is thinner than the first electrode or the black matrix.
