Embodiment Construction
[0023] Preferred embodiments of the present invention will be described in detail with reference to the following drawings. The embodiments described below can be modified in various forms, and the scope of the present invention is not limited to the embodiments described below. The embodiments of the present invention are provided to more completely explain the present invention to those skilled in the art. On the other hand, in the drawings, the thicknesses of films (layers, patterns) and regions are exaggerated for clarity. And, when a film (layer, pattern) is located on, above, below, or on one side of another film (layer, pattern), this may be directly formed on another film (layer, pattern), or another film (layer, pattern) may also be (layers, patterns) intervene between them.
[0024] Embodiments of the present invention disclose that the adhesive material or the adhered material includes an adhesive adjustment layer whose adhesive force is adjusted, and is excellent...

Abstract
Disclosed is a display device using an adhesion control layer, which has excellent scratch-resistance, easily discharges air bubbles, allows proper attachment and detachment, and is stably attached regardless of whether a surface is flat or curved. The device comprises: an adhesive member; an adherend member to which the adhesive member is attached; a detachable layer disposed on one of the adhesive member and the adherend member; and an adhesion control layer to which the detachable layer is detachably attached and which is disposed on one of the adhesive member and the adherend member, wherein the adhesion control layer is disposed on one surface of one of the adhesive member and the adherend member and includes a flat layer covering the whole of the surface and a pattern layer disposedon the flat layer, and the flat layer and the pattern layer have different adhesive forces with respect to the detachable layer.
Description
technical field [0001] The present invention relates to a display device, and more specifically relates to adjusting the adhesive force according to the adhesive adjustment layer, so that the separated display device can be attached not limited to the curved surface and the flat surface. Background technique [0002] Among the display devices, displays such as a liquid crystal display device (LCD), an organic light emitting diode (OLED), a micro light emitting diode display (micro LED), and an electrophoretic display device (EPD) form a screen. Displays are widely used in mobile devices such as mobile phones, smartphones, and tablets, and information processors such as ATMs and automatic kiosks. The display device adopts a portable device with various functions. Adhering materials such as protective sheets (protective films or protective glasses), windows, circuit boards, touch screens, rear covers, etc. in such portable devices are attached and separated from the adhered m...
