  • Publication number: 20090257009
    Abstract: A CF substrate (2) is designed such that at an area of a black matrix (22) that is closer to a TFT substrate (1), a counter electrode (24) does not cover at least a part of a first area that faces source lines (13). Consequently, even when a foreign matter (13a) attaches to the source line (13), it is possible to prevent the foreign matter (13a) from contacting the counter electrode (24). This allows realizing a display panel and a display device in which electric leakage between a line electrode and a counter electrode is prevented even when a foreign matter attaches to a line electrode and a counter electrode.

  • Publication number: 20090159889
    Abstract: The present invention provides a method of manufacturing a TFT substrate, in which method a data signal line is separated into upper and lower regions at a separating point(Q) that is not around above a scan signal line but in a region where an i-layer and an n+ layer formed on a gate insulating film are removed away in a flattened region of a gate insulating film.

  • Publication number: 20090122252
    Abstract: A liquid crystal drop fill device by which liquid crystal panels of different sizes can be easily obtained from a mother glass, and a method for drop filling liquid crystal by using the device is provided in order to increase utilization efficiency of the mother glass. The device 1 includes a stage 3 arranged to support a substrate 2, liquid crystal dispensers 4 and 5 arranged to drop fill liquid crystal on the substrate 2, a first moving unit arranged to support the dispensers 4 and 5 movably in a Y-direction (a moving direction of the dispenser) relative to the stage 3, and second moving units 7 and arranged to support the dispensers 4 and 5 movably in an X-direction (a direction perpendicular to the moving direction) relative to the first moving unit 6, wherein the device 1 further includes a third moving unit 9 arranged to support the dispenser 5 to be further movable in the Y-direction relative to the second moving unit 8.

  • Publication number: 20090066872
    Abstract: In a pixel (1), an oblique part of a capacitor line (Cs) includes a plurality of capacitor electrodes (2a) and a plurality of capacitor electrodes (2b), and the capacitor electrodes (2b) are provided between adjacent capacitor electrodes (2a). An insulating layer including an insulating film (6) is formed on the capacitor electrode (2b), and a pixel electrode (7) is further formed on the insulating layer. A voltage is applied across a liquid crystal between the capacitor electrode (2a) and the pixel electrode (7) so that a storage capacitance is formed which is defined by the capacitor electrode (2b) and the pixel electrode (7). By means of this, it is possible to achieve a TFT substrate, whose producing processes are simplified, for use in a liquid crystal display device in which electric field concentrating patterns of electrodes, via which a voltage is applied across a liquid crystal, are alternately provided at different heights in a thickness direction of a liquid crystal layer.
