摘要： A thin-film transistor includes a substrate, and a gate including a double-layered structure having first and second metal layers provided on the substrate, the first metal layer being wider than the second metal layer by 1 to 4 μm. A method of making such a thin-film transistor includes the steps of: depositing a first metal layer on a substrate, depositing a second metal layers directly on the first metal layer; forming a photoresist having a designated width on the second metal layer; patterning the second metal layer via isotropic etching using the photoresist as a mask; patterning the first metal layer by means of an anisotropic etching using the photoresist as a mask, the first metal layer being etched to have the designated width, thus forming a gate having a laminated structure of the first and second metal layers; and removing the photoresist.

摘要： An organic light emitting display device with enhanced luminous efficiency and color viewing angle and a method of manufacturing the same are disclosed. The method includes forming a first electrode of each of red, green, blue and white sub-pixels on a substrate, forming a white organic common layer on the first electrodes, and forming a second electrode on the white organic common layer, wherein the first electrodes each includes multiple transparent conductive layers and is formed such that a thickness of the first electrode of each of two sub-pixels among the red, green, blue and white sub-pixels is greater than a thickness of the first electrode of each of the other two sub-pixels, and at least two layers excluding the lowermost layer among the multiple transparent conductive layers of each first electrode are formed to cover opposite sides of the lowermost layer.

摘要： Display devices and, in particular, electroluminescent display devices including a lower structure of a bank causing a highly conductive hole injection layer to take on a shape so as to reduce a leakage current, and a method for manufacturing the same are described. An electroluminescent display device includes a substrate having a plurality of pixels, a bank located at a boundary between the subpixels, a first electrode in each subpixel, a separation induction layer between the bank and the first electrode, a p-type layer with a first portion on the bank and a second portion on an emission assembly of the subpixels, and at least one common layer on the p-type layer.
