A structure of a thin film transistor (TFT) planar display panel is disclosed.
The structure includes a light-transmissible substrate, a buffer layer formed on
the light-transmissible substrate, a top-gate TFT structure formed on the buffer
layer and including a channel region, and a light-shielding structure formed between
a back light source and the top-gate TFT structure, and substantially aligned with
the channel region for protecting the channel region from illumination of the back
light source. The process for manufacturing a TFT planar display panel is also disclosed.
