  • Patent number: 9524670
    Abstract: A display apparatus includes: pixels at a display area; dummy pixels at a dummy area; and repair lines coupled to the dummy pixels and connectably arranged to the pixels, each of the dummy pixels including: a driving transistor configured to output a driving current corresponding to a data signal applied to a gate electrode thereof; an emission control transistor between a connection node of a corresponding repair line of the repair lines and the driving transistor, configured to be controlled by an emission control signal; a bypass transistor between the connection node and a first initialization voltage line through which a first initialization voltage is supplied, configured to be controlled by an initialization control signal; and a coupling removal transistor between the connection node and the first initialization voltage line, configured to be controlled by a coupling control signal applied at a different timing from the initialization control signal.

  • Patent number: 8564746
    Abstract: A color filter substrate, a method of manufacturing the same, and a display panel using the color filter substrate are disclosed. The color filter substrate includes a substrate in which pixel areas are defined, color filters formed on the pixel areas and including first holes therein, a common electrode surrounding upper surfaces and sides of the color filters and including second holes to correspond to the first holes, and first black matrices formed in the first holes.

  • Publication number: 20120033150
    Abstract: A liquid crystal display panel and a method of fabricating the same are disclosed. In one embodiment, the liquid crystal display panel includes i) a first substrate and a second substrate facing each other, ii) a liquid crystal layer disposed between the first and second substrates, iii) a color filter disposed between the liquid crystal layer and the second substrate and iv) a black matrix formed on the color filter. The panel may further include i) a sealing member disposed on an outer portion of the liquid crystal layer between the first and second substrates so as to couple the two substrates to each other ii) a plurality of protrusion members formed on the second substrate so as to at least partially overlap with the sealing member iii) a reflective layer formed on the protrusion members and iv) a cover layer formed on the reflective layer so as to cover the reflective layer and the protrusion members.
