Embodiment Construction

[0018] In the drawings, the thickness of layers, films, panels, regions, etc., are exaggerated for clarity of illustration. The same reference numerals denote the same elements in the specification. It will be understood that when an element such as a layer, film, region, or substrate is referred to as being "on" another element, it can be directly on the other element or intervening elements may be present. In contrast, when an element is referred to as being "directly on" another element, there are no intervening elements present.

[0019] Now, an LCD according to an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

[0020] In FIG. 1 , the LCD includes a TFT array panel 100 , a common electrode panel 200 facing the TFT array panel 100 , and an LC layer 3 between them.

[0021] The TFT array panel 100 includes an insulating substrate 110 , a plurality of switching elements (not shown) and a passivation layer 180 fo...

Abstract

A method of manufacturing an LCD includes forming a gate line, depositing a gate insulating layer on the substrate, forming a semiconductor layer on the gate insulating layer, forming a data line and a drain electrode on the semiconductor layer, and forming a pixel electrode connected to the drain electrode including a transparent electrode and a reflecting electrode disposed on a portion of the transparent electrode. The lower layer of the reflecting electrode includes an Ag alloy containing Mo, and the upper layer of the reflecting electrode includes a transparent conductive material such as IZO or ITO. The refraction index of second layer may be larger than that of the LC layer, and light reflected on the surface of the second layer and light reflected on the surface of the first layer may constructively interfere with each other.

Description

[0001] This application claims priority and the benefit of Korean Patent Application No. 10-2005-0117983 filed with the Korean Intellectual Property Office on December 6, 2005, the entire contents of which are hereby incorporated by reference. technical field [0002] The invention relates to a transflective liquid crystal display (LCD) and its display panel, as well as a manufacturing method of the display panel. Background technique [0003] LCD is one of the most widely used flat panel displays. An LCD includes a liquid crystal (LC) layer interposed between two panels with field-generating electrodes. LCDs display images by applying voltages to field-induced electrodes to generate an electric field that determines the orientation of LC molecules, which change the polarization of incident light. This light with varying polarization is either blocked or allowed to pass through the polarizing film, thereby displaying an image. [0004] LCDs fall into the category of non-em...
