An input display is provided in the present invention. The input display includes a thin film transistor (TFT) and a light blocking layer. The TFT includes a low-field electrode, a high-field electrode connected to the low-field electrode with a connecting section, and a field-effect area positioned on the connecting section and connected to the high-field electrode, wherein a PN junction field is formed in the field-effect area when the TFT is switched off. The light blocking layer corresponds to the high-field electrode and hides the field-effect area from all incident light from the TFT.
