Thin film transistor array panel for liquid crystal display
View Patent ↗There are provided two subpixels opposite each other with respect to each data line. A pair of gate lines are provided for each row of pixels. A plurality of subsidiary signal lines are provided between the adjoining columns of the pixels. The data lines and the subsidiary signal lines are alternately arranged between the adjoining columns of the pixels. A storage wire is provided between the adjoining rows of the pixels.
1. A thin film transistor array panel comprising:
a storage line formed over a substrate;
a gate wire formed over the substrate and extending parallel to the storage line, the gate wire comprising a first gate line including a first gate electrode and a second gate line including a second gate electrode;
a data wire formed over and extending perpendicular to the gate wire, the data wire comprising:
a first data line including a first source electrode and a first drain electrode disposed opposite the first source electrode with respect to the first gate electrode;
a second data line including a second source electrode and a second drain electrode disposed opposite the second source electrode with respect to the second gate electrode; and
a data connector that connects the first data line to the second data line;
a first pixel electrode connected to the first drain electrode; and
a second pixel electrode connected to the second drain electrode.
2. The thin film transistor array panel of claim 1 , wherein a shape formed by the first and second gate electrodes, the first and second source electrodes and the first and second drain electrodes has rotational symmetry.
3. The thin film transistor array panel of claim 1 , further comprising:
a first semiconductor island formed over the first gate electrode; and
a second semiconductor island formed over the second gate electrode.
4. The thin film transistor array panel of claim 3 , further comprising:
a first ohmic contact layer formed over the first semiconductor island; and
a second ohmic contact layer formed over the second semiconductor island, each of the first and second ohmic contact layers comprising a first portion and a second portion disposed opposite the first portion with respect to a corresponding one of the first and second semiconductor islands.
5. The thin film transistor array panel of claim 4 , further comprising:
a passivation layer formed over the data wire and having an uneven surface, the first and second pixel electrodes being formed over the passivation layer.
6. The thin film transistor array panel of claim 1 , further comprising:
a first subsidiary member extending from the first data wire; and
a second subsidiary member extending from the second data wire.
