Abstract: Disclosed herein is a process for preparing a metal or nonmetal phthalocyanine by using both microwave and ultrasonic wave energy in the presence of a solvent, or by using microwave energy in the absence of a solvent. Specifically, according to the process, anhydrous phthalic acid, phthalimide, 1,3-diiminoisoindoline, 1,2-dicyanobenzene, an halogen derivative thereof, an alkyl_derivative thereof or an alkoxy derivative thereof is mixed with a metal chloride or an alkoxy metal at 130250° C. for 0.2515 hours by using microwave at a frequency of 0.1-1000 Hz and a power of 100-3,000 W and ultrasonic wave at a frequency of 1-1,000 GHz and a power of 100-5,000 W in the presence of a solvent, or by using microwave at a frequency of 0.1-100 GHz and a power of 100-4,000 W in the absence of a solvent. Further disclosed is an apparatus for preparing a metal or nonmetal phthalocyanine in the absence or presence of solvent.

Abstract: Disclosed herein are a method and an apparatus for preparing oxytitanium phthalocyanine as a charge generating material.

The apparatus comprises: a magnetron 1 capable of generating a frequency of 0.

Abstract: Disclosed herein is a method for preparing oxytitanium phthalocyanine as a charge generating material. The method comprises the steps of mixing 30-100 wt % sulfuric acid and an oxytitanium phthalocyanine crude in a mixing ratio between 100:1 and 1:1, homogeneously grinding the mixture in a wet grinder filled with zirconia or glass beads as grinding media at ?20° C.˜60° C. for 0.1˜24 hours, and removing the grinding media from the ground mixture using a solvent. According to the method, oxytitanium phthalocyanine usable as a high-quality charge generating material can be prepared without the use of expensive and difficult-to-handle reactants, such as trifluoroacetic acid and pentafluoropropionic acid. Further disclosed is an oxytitanium phthalocyanine charge generating material prepared by the method.

Abstract: There are disclosed an organic electro luminescence display device that is adaptive for preventing a defect in forming a barrier rib, and a fabricating method thereof. An organic electro luminescence display device according to an embodiment of the present invention includes first and second electrodes formed to cross each other with an organic light emitting layer therebetween; a barrier rib which crosses the first electrode and is parallel to the second electrode; and an insulating film which is located between the barrier rib and the first electrode and defines an area of forming the organic light emitting layer, and wherein the insulating film has at least one groove which is provided in a contact area with the barrier rib.
