Active matrix substrate, x-ray sensor device, display device

An active matrix substrate comprising:

• a first signal line and a second signal line which are aligned in a column direction in which the first signal line and the second signal line extend;
• a first transistor and a second transistor;
• and
• a first electrode and a second electrode, wherein
• the first signal line being connected via the first transistor to the first electrode, and the second signal line being connected via the second transistor to the second electrode;
• the first signal line having a first end which is one of both ends of the first signal line and faces the second signal line, the first end including a tapered part which is tapered toward the second signal line;
• and
• the tapered part is formed by causing a part of a rim of the first end to have a shape of a polygonal line:
• (i) which protrudes toward the second signal line, or (ii) which protrudes away from the second signal line.
