Abstract
A TFT array is formed on a glass substrate (step P ). A surface protection layer is formed on the glass substrate so as to cover the TFT array (step P ). The glass substrate is divided to form active matrix, substrates with the surface protection layer being provided (step P ). The divided active matrix substrate is chamfered along its edges (step P ). The surface protection layer is removed from the active matrix substrate (step P ). An X-ray conductive layer is formed on the TFT array where the surface protection layer has been removed (step P ). By these steps, pollutants produced during the division and chamfering of the glass substrate are prevented from polluting the TFT array and the X-ray conductive layer, and the active element array and the semiconductor layer is prevented from deteriorating in terms of performance in manufacturing process for a two-dimensional image detector.
