Embodiment Construction

[0035]Hereinafter, the present invention will be described more fully with reference to the accompanying drawings, in which the embodiments of the present invention are shown. However, the present invention can be implemented in a variety of different forms, and should not be construed as being limited by the various embodiments presented here. More precisely, these embodiments are provided to make this disclosure thorough and complete, and to fully convey the protection scope of the present invention to those skilled in the art. The same reference numerals denote the same elements.

[0036] It should be understood that when an element is referred to as being on ("on") another element, it may be directly on the other element, or there may be intervening elements therebetween. In contrast, when an element is said to be directly on another element, there are no intervening elements. As used herein, the term "and / or" encompasses any or all combinations of one or more related listed i...

Abstract

A display panel includes a first substrate, a touch spacer, a common electrode and a sensing electrode. The second substrate faces the first substrate, the touch spacer is disposed on a first substrate, the common electrode is disposed on the touch spacer, and the sensing electrode is disposed on a second substrate directly under the touch spacer. A surface, facing the first substrate, of the sensing electrode includes protrusions which protrude toward the first substrate.

Description

[0001] This application claims the priority of Korean Patent Application No. 2008-1205 filed on January 4, 2008, and all the benefits arising therefrom according to 35 U.S.C. §119, and all the contents thereof are incorporated herein by reference. Technical field [0002] The present invention relates to a display panel, and more particularly, the present invention relates to a liquid crystal display having a touch panel that prevents errors in detection coordinates corresponding to a touch point on the touch panel. Background technique [0003] Generally, a touch panel is used as an input device for a display device such as a liquid crystal display, a field emission display, a plasma display panel, or an electroluminescence display. [0004] Based on the operation method of the touch panel, the touch panel can be classified as a capacitive touch panel or a resistive thin film touch panel. In particular, the capacitive touch panel detects electric charges generated between a trans...
