Abstract: The present invention discloses a method for manufacturing an organic EL device on a transparent substrate including a display region and a non-display region, the display region having pixel regions, includes forming first electrodes, and first and second leads on the transparent substrate, the first electrode spaced apart from each other, connected with the first leads, and formed on the display region, the first and second leads formed on the non-display region. Then, a photoresist layer is deposited over the whole surface of the transparent substrate while covering the first electrode. A first mask and a second mask are aligned on the front side and the back side of the transparent substrate. An insulating layer and partition walls are formed on a region of the display region other than the pixel regions and an EL light-emitting layer is formed on the pixel regions.

Abstract: The present invention provides novel, improved retroviral vectors which can be used for gene therapy, more specifically, retroviral vectors which are not only safer, more versatile, and more convenient than any other existing vectors, but they also drive high levels of gene expression and high viral titer. In retroviral vectors of the present invention, gag and env coding sequences are deleted, and all or part of U3 can be readily substituted with heterologous, non-retroviral promoter elements. Furthermore, at least one internal ribosome entry site is employed to express more than one genes, and multicloning sites are placed in an insertion site for cloning of a heterologous promoter or a foreign gene.
