Problems solved by technology

However, when the thickness of the transparent substrate included in the liquid crystal cell is reduced to reduce the thickness of the liquid crystal cell, there is a problem that bending of the liquid crystal display device may occur due to stress applied by a polarizing plate.

Embodiment Construction

[0023] Throughout the specification of this application, when an element is disposed "on" another element, this includes not only cases where the one element is in contact with the other element, but also cases where there is another element between the two elements.

[0024] In the entire specification of the present application, when a section "includes" one constituent element, unless specifically described otherwise, it does not mean that the other constituent element is excluded, but it means that the other constituent element may also be included.

[0025] Throughout the specification of the present application, "N / 5mm", which is a unit of shrinkage stress, can be converted into a general unit of shrinkage stress used in the art through unit conversion. For example, "N / 5mm" as a unit of shrinkage stress can be converted to N / mm, N / cm, N / m, N / inch, kgf / mm, kgf / cm, kgf / m, kgf / inch, and the like.

[0026] The inventors found that, in the case of a liquid crystal display dev...

Abstract

The present invention relates to a polarizing plate capable of suppressing the occurrence of bending of a liquid crystal display device, and a liquid crystal display device including the same. According to an aspect of the present invention, the polarizing plate includes: a polarizer; and a polarizer protective film provided on one surface of the polarizer, wherein the polarizer protective film is at 0RH% to 20RH% It has a thermal shrinkage stress of 2.5N / 5mm to 8N / 5mm after being heated at 70°C under the conditions of .

Description

technical field [0001] This specification claims priority to and the benefit of Korean Patent Application No. 10-2017-0094369, filed with the Korean Intellectual Property Office on July 25, 2017, the entire contents of which are incorporated herein by reference. [0002] The present invention relates to a polarizing plate and a liquid crystal display device including the same. Background technique [0003] Recently, as various portable devices (eg, mobile phones or laptop computers) and information electronic devices (eg, HDTV) that realize high-definition and high-quality images are developed, there is a demand for flat panel display devices applied to these devices gradually increase. As flat panel display devices, liquid crystal displays (LCDs), plasma display panels (PDPs), field emission displays (FEDs), organic light emitting diodes (OLEDs), and the like have been actively studied, but liquid crystal displays (LCDs) are currently Special attention has been paid to th...
