Benefits of technology

The patent provides a polarizing plate and LCD that can reliably function even in high-temperature, high-humidity environments. The patent reduces or prevents bending of the polarizing plate and LCD to ensure their high reliability.

Problems solved by technology

However, the TAC films have relatively high moisture permeability, and may thus cause the polarizing plate to be bent, especially under relatively high-temperature, high-humidity conditions.

Abstract

A polarizing plate includes a first glass plate; a second glass plate facing the first glass plate; and a polarizing device between the first and second glass plates. An external surface of at least one of the first and second glass plates, which is not in contact with the polarizing device, has a root mean square surface roughness of about 1 nanometer or less.

Description

[0001]This application is a divisional application of U.S. application Ser. No. 14 / 308,928 filed Jun. 19, 2014, which claims priority to Korean Patent Application No. 10-2014-0013104 filed on Feb. 5, 2014, and all the benefits accruing therefrom under 35 U.S.C. § 119, the disclosure of which is incorporated herein by reference in its entirety.BACKGROUND1. Field[0002]Exemplary embodiments relate to a polarizing plate, a liquid crystal display (“LCD”) including the polarizing plate and a method of fabricating the polarizing plate.2. Description of the Related Art[0003]Polarizing plates are commonly used in LCDs to control the vibration direction of light and thus to visualize a display pattern of the LCDs. LCDs boast of their wide range of application, ranging from small devices to laptop computers, LCD monitors, LCD color projectors, LCD televisions (“TVs”), navigation systems for automobiles, personal phones and various measuring equipment for indoor and outdoor use. Particularly, L...
