ORGANIC ELECTROLUMINESCENCE DEVICE AND PATTERNING METHOD OF PIXELS THEREOF

摘要

PURPOSE: An organic electroluminescence device and a patterning method of pixels thereof are provided to reduce processes and to achieve improved accuracy of spacing and shape of pattern. CONSTITUTION: A patterning apparatus for an organic electroluminescence device comprises a printing roll(114); an APR resin plate attached to the rotating surface of the printing roll, and patterned to be parallel to a printing direction(124) and lengthwise direction of red, green and blue pixel patterns(126a,126b,126c); an anilox roll for applying an organic material to the APR resin plate; a doctor blade for adjusting the organic material to have a uniform thickness; a dispenser for providing the organic material to the anilox roll; a glass substrate(112) contacting the APR resin plate; and a printing table arranged beneath the glass substrate in such a manner that the printing table is movable.
