A polarizing plate and a liquid crystal display device are provided which can prevent abrasion since the roughness and coefficient of friction of an outer base material of a polarizing plate are designed depending on the surface hardness of the outer base material by conducting studies and tests that are conducted into factors causing abrasion between the polarizing plate and an optical sheet and taking the results into account. Therefore, the problem of abrasion between the polarizing plate and the optical sheet associated with slim-profile liquid-crystal display devices can be solved, thereby achieving a slim design without cost increase.

Liquid-crystal display device having polarizing plate for reducing smudges

The present disclosure provides a liquid crystal display device including a light source unit which supplies light to a liquid crystal panel, a lower polarizing plate disposed below the liquid crystal panel, an upper polarizing plate, a light absorption filter, and a fluorescent filter disposed above the liquid crystal panel. According to the present disclosure, when a laser pointer in a visible ray region illuminates after implementing a display image, light irradiated by the laser is absorbed by the fluorescent filter and the light absorption filter to convert the light into red, green, and blue light to be emitted, thereby improving visibility in accordance with illumination of a laser pointer.

Liquid crystal display device

The present disclosure relates to an integrated polarizer film and a liquid crystal display integrated with the same polarizer film. The liquid crystal panel according to the present disclosure comprises: a liquid crystal panel; an upper polarizer film having a first light transmission axis and disposed on a top surface of the liquid crystal panel; a light diffusion layer embedded lower polarizer film having a second light transmission axis and disposed on a bottom surface of the liquid crystal panel; and an upper prism sheet laminated under the bottom surface of the light diffusion layer embedded lower polarizer film by a low refractive adhesive layer, and including a prism pattern having a first prism pattern and a second prism pattern smaller than the first prism pattern, wherein topmost portions of the first prism pattern are immersed into the low refractive adhesive layer, wherein the upper prism sheet is combined with the light diffusion layer embedded lower polarizer film, and wherein an air layer is inserted between the low refractive adhesive layer and the second prism pattern.

Integrated polarizer film and liquid crystal display integrated with the same polarizer film

Disclosed is a liquid crystal display device and a method of manufacturing the same. The liquid crystal display device includes first and second substrates, a liquid crystal layer between the first and second substrates, and a first polarizing layer on the first substrate, wherein the first polarizing layer includes a plurality of carbon nanotubes aligned in a first direction.
