  • Patent number: 8203539
    Abstract: A display panel and a method of manufacturing the same are provided, which can prevent the deterioration of input sensitivity to the panel, and maximize the aperture ratio of the panel. The display panel includes a first substrate, a gate line and a data line crossing each other on the first substrate, in a manner that the gate line and the data line are electrically insulated from each other. The display panel further comprises a first sensor wire formed in parallel to the data line, a second sensor wire formed to overlap the data line in parallel to the data line, a second substrate arranged opposite to the first substrate, and a sensor spacer formed on the second substrate to project toward the first substrate.

  • Patent number: 8081279
    Abstract: Disclosed is a liquid crystal display device including a first substrate where pixel areas are defined, a second substrate facing the first substrate, liquid crystals aligned between the first and second substrates, and spacers that maintain a gap between the first and second substrates. The pixel areas are divided into a plurality of domains along the alignment direction of the liquid crystals by way of domain dividers. Optical characteristics are compensated in different domains, so that the viewing angle of the liquid crystal display device is increased. The display quality of the liquid crystal display device is improved by adjusting the shape and position of the domain dividers and the spacers.

  • Publication number: 20090091546
    Abstract: A display device with a built-in touch screen panel and a method of manufacturing the same are presented. The display includes a first substrate and a second substrate facing each other, a first sensing electrode and a second sensing electrode disposed on the first substrate and spaced apart from each other, and a conductive spacer disposed on the second substrate corresponding to each of the first and second sensing electrodes. The display device is less sensitive to misalignment between the first and second substrates during the manufacturing process compared to a conventional device, and therefore has a lower defect rate than the conventional device.
