Embodiment 1
[0044] refer to figure 1 , which shows a schematic structural view of a thin film transistor according to Embodiment 1 of the present invention.
[0045] The thin film transistor includes: a first gate 101, a source 102 and a drain 103 located on the same layer on the substrate, a first gap is formed between the source 102 and the first gate 101, and the drain A second gap is formed between the electrode and the first grid.
[0046] A gate insulating layer 104 covering the first gate.
[0047] The semiconductor layer 105 covering the source 102 , the gate insulating layer 104 , the drain 103 and filling the first gap and the second gap.
[0048] In this structure, the substrate can be formed of a transparent glass material whose main component is silicon dioxide. The material forming the substrate is not limited to the transparent glass material, and can also be a transparent plastic material. The substrate is preferably a glass substrate.
[0049] In the same layer on the ...
