Array substrate and display apparatus using the same

A display apparatus, comprising:

• an array substrate;
• an opposite substrate disposed opposite to the array substrate;
• and
• a display layer disposed between the array substrate and the opposite substrate;
• wherein the array substrate comprises a substrate, a plurality of scan lines and a plurality of data lines, the scan lines are disposed on the substrate in a first direction, the data lines are disposed on the substrate in a second direction, the data lines are electrically insulated and intersected with the scan lines thereby defining a plurality of pixel structures, the first and second directions are mutually perpendicular, and each pixel structure comprises a first thin film transistor and a pixel electrode, the first thin film transistor is disposed on the substrate and comprises a first gate, a first source and a first drain, the first gate is connected to the corresponding scan line, the first source is disposed above the first gate and partially overlapping the first gate, one end of the first source is connected to the corresponding data line, the first drain is disposed above the first gate and comprises at least one first concavity, and a portion of the first source is disposed in the at least one first concavity, the second thin film transistor is disposed on the substrate and comprises a second gate, a second source and a second drain, the second gate is connected to the corresponding scan line, the second source is disposed above the second gate and connected to the first drain, the second source comprises at least one second concavity, the second drain is disposed above the second gate and partially overlapping the second gate, and a portion of the second drain is disposed in the at least one second concavity, the pixel electrode is connected to the second drain.
