Embodiment Construction

[0028] The invention will now be described more fully hereinafter with reference to the accompanying drawings, in which preferred embodiments of the invention are shown. However, this invention may be embodied in many different forms and should not be meant to be limited to the embodiments set forth herein.

[0029] In the drawings, the thicknesses of layers and regions are exaggerated for clarity. Throughout the specification, like numbers refer to like elements. It will be understood that when an element such as a layer, film, region, substrate or panel is referred to as being "on" (another element), it can be directly on the other element or intervening elements may also be present. In contrast, when an element is referred to as being "directly on" (another element), there are no intervening elements present.

[0030] The BEF according to the embodiment of the present invention and the method of preparing the BEF are described below with reference to the accompanying draw...

Abstract

A brightness enhancement film (BEF) is provided, the BEF includes a polymer film having dopants, wherein a concentration of the dopants gradually varies with respect to a depth of the BEF.

Description

[0001] Cross entrants to related applications [0002] This application claims priority and benefits from Korean Patent Application No. 10-200400113307 filed on December 27, 2004, which is hereby incorporated by reference for all purposes as if fully set forth herein. technical field [0003] The present invention relates to an improved brightness enhancement film and its preparation method. Background technique [0004] A liquid crystal display (LCD) includes a transistor panel having gate lines, data lines, switching elements such as thin film transistors (TFTs), and pixel electrodes; a color filter panel opposite to the transistor panel, the color filter panel There are color filters and a common electrode; and a liquid crystal (LC) layer therebetween. [0005] The pixel electrodes are connected to the TFTs and supplied with data voltages through the data lines. The common electrode covers the entire surface of the color filter panel and is supplied with a common voltag...
