Problems solved by technology

However, under long-term operation, damage still occurs on the display surface of the display device
That is, the hard coat layer prevents damage in the initial operation stage, however, damage still occurs in the display device due to the stress accumulation of long-term operation

Embodiment Construction

[0020] Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings.

[0021] figure 1 is a schematic cross-sectional view of a display device according to the present invention.

[0022] refer to figure 1 , the display device 100 according to the present invention includes a display panel 110 and a hard coat layer 120 on one side of the display panel 110 . That is, the hard coat layer 120 faces the display surface of the display panel 110 and forms the outermost layer of the display device 100 .

[0023] The hard coat layer 120 includes a silicon compound (ie, silicide). Silicon compounds contain disulfide groups (-S-S-) and siloxane groups (-Si-O-Si-) for self-healing properties. Two siloxane groups are bonded on both sides of the disulfide group, allowing the disulfide group to be protected. In other words, adjacent siloxane groups are bound or linked by disulfide groups.

[0024] When stress is appl...

Abstract

The invention relates to a hard-coating layer, a method of fabricating the same and a display device including the same. Described herewith is a hard-coating layer comprising a binder; and a silicon compound dispersed in the binder and including a disulfide group conncecting adjacent siloxane groups, a method of manufacturing the hard-coating layer, and a display device included the same.

Description

[0001] This application claims priority to Korean Patent Application No. 10-2015-0120575 filed in Korea on Aug. 26, 2015, which is hereby incorporated by reference. technical field [0002] The present invention relates to a display device, and more particularly, to a hard coat layer having self-healing properties (performance), a method of manufacturing the hard coat layer, and a display device including the hard coat layer. Background technique [0003] As society has truly entered the information age, various display devices for displaying images are required. Flat panel display devices such as LCD devices, plasma display panels (PDP) and organic light emitting diode (OLED) display devices tend to have superior capabilities over cathode ray tube (CRT) devices: thin profile, light weight, low power consumption, and the like. Such devices have been extensively researched and developed to replace CRT display devices. [0004] Recently, portable display devices such as mobil...
