Description

FIELD OF INVENTION

This present disclosure generally relates to the field of display technology, and in particular to a polarizer and a display device.

BACKGROUND OF INVENTION

Liquid crystal display televisions (LCD TV) have become very popular, and human beings are natural visual animals. Most consumers pay special attention to the appearance when they choose to buy LCD TVs. When “light” and “thin” become the mainstream, bezel-free TVs are undoubtedly more in line with the general public aesthetic. Moreover, in addition to the stylish appearance, the bezel-free TVs can also be regarded as a kind of subversion in terms of viewing effects. As the width of the bezel is reduced, the user can have a wide field of vision when enjoying the TV screen. Even in the same screen size, narrow bezel TVs and bezel-free TVs make people feel much larger sizes and better viewing effects.

However, when the current mass-produced liquid crystal panels are used to manufacture bezel-free display devices, because there is no protection and shielding for the bezel, there are many problems, such as edge light leakage or strabismus light leakage, which affect the display quality of the display device.
