Embodiment Construction

[0039] The present invention relates to a light-shielding pattern-embedded window film, which comprises: a base film; a first hard coat layer and a second hard coat layer sequentially laminated on one surface of the base film; A light-shielding pattern at an outer region between the hard coat layer and the second hard coat layer. The light-shielding pattern-embedded window film has the light-shielding pattern and has no level difference caused by it, so it is easier to be laminated with other members and realize the light-shielding pattern.

[0040] Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. However, since the drawings attached to the present invention are only used to illustrate one of various preferred embodiments of the present invention, and thus help to further understand the technical spirit of the present invention in conjunction with the above-mentioned content of the invention, i...

Abstract

The present invention relates to a window film and a method for preparing same and, more specifically, to a window film, having a light shielding pattern therein, comprising: a base film; and a firsthard coating layer and a second hard coating layer which are sequentially laminated on one side of the base film. The window film has a light shielding pattern on an outer area between the first hardcoating layer and second hard coating layer. The window film has the light shielding pattern and does not have any step-shaped portion due to same and thus enables easier lamination with other membersand as well as enhanced light shielding pattern production.

Description

technical field [0001] Embodiments of the present invention relate to a window film and a preparation method thereof, in particular to a window film and a preparation method thereof which do not cause step differences when rubbing other components. Background technique [0002] Recently, various display devices capable of displaying information have been developed. The display device may include a liquid crystal display device, an organic electroluminescence display device, a plasma display panel, a field emission display device, or the like. [0003] In addition, flexible displays that are thinner and lighter than existing panels and bendable and foldable by using polymer films instead of glass substrates have been studied. In the past, touch-sensing patterns were formed on glass substrates, but due to the limitation of non-flexibility, glass substrates are gradually replaced by film materials. In flexible displays, the biggest problem lies in the overall thickness of the...
