Problems solved by technology

[0015] However, the use of the aforementioned holographic diffuser is disadvantageous in the case where low-refractive index organic materials have poor adhesion and forming an overcoat layer on top of the holographic patterned scattering layer to maintain the same shape is a complicated and time-consuming process.
Therefore, the LCD device equipped with the aforementioned holographic diffuser is expensive and has poor reliability

Abstract

A liquid crystal display device includes a liquid crystal cell, a first polarizer under the liquid crystal cell, a backlight under the first polarizer, and a holographic diffuser over the liquid crystal cell. The holographic diffuser includes a spacer and a diffusing layer over the spacer. The spacer includes an open portion and a lower surface of the diffusing layer includes a holographic pattern.

Description

[0001] This application claims the benefit of Korean Patent Application No. 2001-69444 filed on November 8, 2001, which is incorporated herein by reference in its entirety. technical field [0002] The present invention relates to a liquid crystal display (LCD) device, and more particularly to an LCD device including a diffuser. Background technique [0003] Due to their small size, light weight, and low power consumption, flat panel display (FPD) devices have become a subject of much research in the field of information technology. Among many types of FPD devices, LCD devices have excellent color, high definition, and display characteristics, and they are used in devices such as notebook personal computers (PCs), desktop PCs, and the like. Generally, an LCD device includes first and second electrode supporting substrates interconnected and spaced apart from each other by a layer of liquid crystal material. LCD devices utilize anisotropic optical properties of liquid crysta...
