Embodiment Construction

[0042] In the following detailed description, certain exemplary embodiments of the present invention have been shown and described, simply by way of illustration. As those skilled in the art would realize, the described embodiments may be modified in various different ways, all without departing from the spirit or scope of the present invention. Accordingly, the drawings and descriptions are to be regarded as illustrative in nature and not restrictive. In addition, when an element is referred to as being "on" another element, the element may be directly on the other element, or the element may be indirectly on the another element with one or more intervening elements interposed therebetween. on the other component. In addition, when an element is referred to as being “connected to” or “coupled to” another element, the element may be directly connected to the other element, or one or more elements may be interposed therebetween. An intermediate element is thus indirectly conn...

Abstract

A liquid crystal display (LCD) having a built-in touch screen panel includes a first substrate having a plurality of pixels, wherein each of the pixels comprises a thin film transistor and a pixel electrode; a plurality of common electrode patterns corresponding to the pixel electrodes and spaced from each other along a second direction; a second substrate facing the first substrate, the second substrate having color filter patterns, wherein the color filter patterns are arranged to correspond to the pixels; a plurality of black matrix patterns between the color filter patterns, the plurality of black matrix patterns being spaced from each other along a first direction crossing the second direction; and a liquid crystal layer between the first and second substrates, wherein the plurality of common electrode patterns and at least one of the black matrix patterns are used as driving electrodes and sensing electrodes, respectively.

Description

[0001] Cross References to Related Applications [0002] This application claims priority and benefit from Korean Patent Application No. 10-2010-0106736 filed with the Korean Intellectual Property Office on Oct. 29, 2010, the entire contents of which are hereby incorporated by reference. technical field [0003] One aspect of the invention relates to liquid crystal displays (LCDs). Background technique [0004] The touch screen panel is an input device that allows a user's instruction to be input by selecting instruction content displayed on a screen of an image display or the like using a user's hand or an object. The user's hand or object directly contacts the touch screen panel at the contact location. [0005] For this, a touch screen panel is formed on the front of the image display to convert a contact position into an electric signal. Accordingly, the instruction content selected at the contact position can be input to the image display as an input signal. [0006]...
