    • An electroluminescent (EL) display device and a method of fabricating the same are provided. The device includes a substrate; a plurality of pixel electrodes disposed on the substrate; a pixel defining layer disposed on the pixel electrodes and having an opening part exposing a predetermined part of each of the pixel electrodes; and at least one barrier layer comprised in and/or on the pixel defining layer. In this device, the pixel defining layer includes at least one barrier layer in order to reduce the amount of outgas from the pixel defining layer and prevent degradation of an emission portion due to the outgas. Also, the pixel defining layer is formed to a sufficiently small thickness to facilitate a subsequent process using a laser induced thermal imaging (LITI) process.
    • 提供一种电致发光(EL)显示装置及其制造方法。 该装置包括基板; 设置在所述基板上的多个像素电极; 设置在所述像素电极上并具有使每个所述像素电极的预定部分露出的开口部的像素限定层; 以及包含在像素限定层中和/或上的至少一个势垒层。 在该装置中,像素限定层包括至少一个阻挡层,以便减少来自像素限定层的排气量,并防止由于排出气体引起的排放部分的劣化。 此外,像素限定层形成为足够小的厚度以便于使用激光诱导热成像(LITI)工艺的后续处理。
