Patent Images
1. An electromagnetic wave detecting element comprising:
- a substrate including a plurality of scan lines and a plurality of signal lines disposed to intersect one another, and TFT switching elements provided at respective intersection portions of the scan lines and the signal lines;
a first flattening film formed to cover the TFT switching elements of the respective intersection portions on the substrate, and flattening a surface;
sensor portions provided on the first flattening film to correspond respectively to the intersection portions, and connected respectively to the TFT switching elements, and generating charges as a result of electromagnetic waves that are an object of detection being irradiated; and
a second flattening film formed to cover the sensor portions on the first flattening film and a region on the substrate at which the first flattening film is formed, and flattening a surface.

Abstract
The present invention provides an electromagnetic wave detecting element that can suppress occurrence of cracking at a substrate peripheral portion, and occurrence of breakage of lead-out wires. An interlayer insulating film is formed so as to cover TFT switches on a substrate. An interlayer insulating film is formed so as to cover semiconductor layer of sensor portions that generate charges due to electromagnetic waves that are an object of detection being irradiated, and cover a region on the substrate where the interlayer insulating film is formed.
