Abstract

A method for manufacturing an LCD device is disclosed, which has a reflective electrode having protrusions formed by simplified manufacturing process steps, thereby improving reflectivity. The method includes: forming a first insulating layer on a substrate; forming a photoresist layer on the first insulating layer, wherein the photoresist layer has a plurality of rounded protrusions and rounded valleys; forming a plurality of rounded protrusions and rounded valleys on the first insulating layer by etching the first insulating layer and the photoresist layer; and forming a reflective electrode on the first insulating layer.

Description

[0001] This application claims the benefit of Korean Patent Application No. P2002-44657 filed on July 29, 2002, which is hereby incorporated by reference for all purposes to which this application relates. technical field [0002] The present invention relates to a method of manufacturing a liquid crystal display (LCD) device, and more particularly, to a method of manufacturing an LCD device with improved reflectance. Background technique [0003] With the development of the information society, the demand for various display devices is increasing. Therefore, much effort has been made in researching and developing various flat panel display devices such as liquid crystal displays (LCDs), plasma display panels (PDPs), electroluminescent displays (ELDs), and vacuum fluorescent displays (VFDs), and these Certain types of flat panel display devices have been used in displays for various devices. [0004] Among various flat panel display devices, LCD devices are most widely used...
