    • Disclosed are an organic light emitting display device with improved yield and processing efficiency, which includes an interlayer capable of being separated into a hydrophilic region and a hydrophobic region on top of a hole injection layer in an organic light emitting device and a plurality of layers including a light emitting layer and which is fabricated without using a shadow mask, as well as a method for manufacturing the same. The manufacturing method includes preparing a substrate having a plurality of pixel regions defined in a matrix form, arranging an anode in each of the pixel regions, forming a hole injection layer on the anode by the solution process, forming an interlayer with hydrophobic properties on the hole injection layer by a solution process, selectively UV irradiating the interlayer to define a hydrophilic region on the interlayer, forming a light emitting layer on the interlayer by the solution process, and arranging a cathode on the substrate having the light emitting layer.
    • 公开了一种具有提高的产率和加工效率的有机发光显示装置,其包括能够分离成有机发光装置中的空穴注入层的顶部的亲水区域和疏水区域的层间,以及包括 在不使用荫罩的情况下制造发光层,以及其制造方法。 该制造方法包括制备具有以矩阵形式限定的多个像素区域的基板,在每个像素区域中布置阳极,通过溶液法在阳极上形成空穴注入层,在其上形成具有疏水性的中间层 通过溶液法选择性地UV照射中间层以在中间层上限定亲水区域,通过溶液法在中间层上形成发光层,并在具有发光层的基板上设置阴极。
