  • Publication number: 20030203527
    Abstract: An electro-luminescent display and a method of manufacturing thereof prevents the formation of a barrier interface between the anode electrode and the electro-luminescent layer by placing the electro-luminescent layer directly on the anode electrode so that there is no need to etch a subsidiary layer so that the electro-luminescent layer and the anode electrode have excellent electrical contact. The elimination of this etching step prevents damage to the anode electrode caused by collision of ions with the anode electrode during the etching process. Further, etch remainders or contaminant particles that exist in the etchant gas are prevented from accumulating on the anode electrode. Thus, the charge carriers of the anode are easily transported across the interface between the anode electrode and the electro-luminescent layer so as to greatly improve the expected life span, the brightness, and the efficiency of the electro-luminescent display.

    Abstract: A method is provided for manufacturing a liquid crystal display having a gate bus line, a data bus line, and a switching element with a drain electrode on a substrate. The method includes the steps of forming a protection layer over the substrate to cover the gate bus line, the data bus line, and the switching element, depositing a first layer on the protection layer, the first layer having a thermal expansion coefficient smaller than that of the protection layer, and depositing a second layer on the first layer, the second layer having a thermal expansion coefficient substantially consistent with that of the first layer. The method further includes the steps of removing portions of the second layer on the first layer to form a desired pattern of the second layer, removing portions of the first layer using the patterned second layer as a mask to form a desired pattern of the first layer, and removing the second layer remaining on the patterned first layer.
