  • Patent number: 10318031
    Abstract: A display device integrated with a touch screen panel including a first substrate, a first guard ring pattern, an insulating layer, and a second guard ring pattern. The first substrate includes a touch region. The first guard ring pattern is positioned at a perimeter of the touch region. The insulating layer is positioned at a perimeter of the first guard ring pattern. The insulating layer is separated from an edge of the first substrate by a first distance. The second guard ring pattern is positioned over each of the first substrate and the insulating layer.

  • Patent number: 8570466
    Abstract: There are provided a thin film transistor substrate for transflective liquid crystal display device (LCD) and a manufacturing method thereof, which can reduce manufacturing cost and simplifying manufacturing processes. In the method, a thin film transistor is formed on a reflection region of a device substrate defined by the reflection region and a transmission region. A passivation layer is formed on the thin film transistor so as to expose a drain electrode of the thin film transistor and to cover the thin film transistor. A pixel electrode is formed on the transmission and reflection regions. The pixel electrode has a structure of a first pixel electrode electrically connected to the drain electrode and a second pixel electrode formed to have an embossed pattern on the first pixel electrode. A reflective layer is formed on the second electrode pixel having the embossed pattern on the reflection region.
