Embodiment Construction

[0046] The present invention involves the use of intrinsic polarizers adjacent to either the front or rear surface, or the front and rear surfaces, of the liquid crystal display element layer. Alternatively, a thin layer or encased iodine polarizer can be placed adjacent to one or both surfaces of the liquid crystal display element layer.

[0047] figure 2 A liquid crystal display stack 50 of the present invention is shown. Both sides of the liquid crystal display element layer 52 are coated with adhesive layers 54 and 56, for example, layers of pressure-sensitive adhesive such as Polatechno AD-20, to fix the polarizing structure on the liquid crystal display element layer, similar to figure 1 The liquid crystal display stack 10 shown in . On the viewing side of the liquid crystal display stack 50, an internal polarizer 58, preferably a K-type or thin KE-type polarizing plate, is attached to the liquid crystal display element layer 52 by a layer 56 of adhesive. K-type pola...

Abstract

The invention relates to polarizers for use with liquid crystal displays. A liquid crystal display structure includes a liquid crystal display cell having a front surface and a back surface. One or more intrinsic polarizers lacking protective coatings thereon, such as K-type polarizers and thin KE polarizer sheets, are disposed adjacent to the front and back surfaces of the liquid crystal display cell. Alternatively, thinly cladded or encased iodine polarizers are disposed adjacent to the front and back surfaces of the liquid crystal display cell. The liquid crystal display structure may be used in conjunction with other optical display elements to enhance the brightness and contrast of the liquid crystal display.

Description

[0001] The patent application for this invention is the international application number PCT / US02 / 11962, the international application date is April 17, 2002, the application number entering the Chinese national phase is 02813453.2, and the invention name is "polarizer for liquid crystal display device" The divisional application of the invention patent application. technical field [0002] The present invention relates to liquid crystal display devices, and more particularly, to polarizers for liquid crystal display devices. Background technique [0003] Liquid crystal display devices are optical display devices used in devices such as portable computers, handheld calculators, and digital wristwatches. A typical liquid crystal display device includes a liquid crystal display element layer and an electrode matrix disposed between a pair of light absorbing polarizers. The liquid crystal display element layer includes, for example, molecules of twisted nematic or super twiste...
