Abstract

A polarized light sheet can be used to improve LCD of nonuniform display caused by nonuniform dyeing. The dyeing bath with concentration of iodine or the dichroic dyestuff bigger than 0.02 wt.% should be used to control its temperature in the range of 15-50 degrees C and to control the stretching multiplying power less than 5 times as well as agitating the bath solution while dyeing, when the polyvinyl alcohol film is under the dyeing course.

Description

Technical field

[0001] The present invention relates to a polarizing plate and a liquid crystal display, and the polarizing plate is used for a liquid crystal display (hereinafter referred to as "LCD") in which unevenness of display, particularly unevenness of dyeing, is improved. Background technique

[0002] LCDs are used in personal computers, etc., and their usage has increased dramatically in recent years. LCD has a wide range of uses, and in recent years it has also been used in monitors.

[0003] However, compared to the use of personal computers, LCDs for monitors have increased screen size and increased panel brightness (luminance). In addition, LCDs for monitors are not only used for individuals like personal computers, but also have more opportunities for viewing by multiple people. Since they are viewed not only from the front but also from an oblique direction, a display with a higher viewing angle is required. In addition, because the monitor requires a bright scree...
