Active matrix substrate and display panel

An active matrix substrate comprising:

• a pixel section;
• a pixel connection line connected to the pixel section;
• a test circuit connected to the pixel connection line and configured to test the pixel section, the test circuit including a source-side test line that is connected to a source electrode of a test switching component and a gate-side test line that is connected to a gate electrode of the test switching component;
• a terminal that is disposed such that the test circuit is present between the terminal and the pixel section and to which a signal to be supplied to the pixel connection line is input;
• a terminal connection line connecting the pixel connection line to the terminal, at least a part of the terminal connection line overlapping the source-side test line and the gate-side test line of the test circuit;
• and
• an insulation film at least disposed between an overlapping portion of the test circuit and the terminal connection line, wherein
• the pixel section includes pixels arranged in a matrix,
• the pixels include pixel electrodes to which a potential according to a supplied signal is applied, and a common electrode to which a common potential is applied,
• the common electrode includes separated common electrodes that are arranged in a matrix and in an area ranging the pixel electrodes,
• the pixel connection line includes multiple pixel electrode pixel connection lines connected to the pixel electrodes and multiple common electrode pixel connection lines connected to the respective separated common electrodes,
• the terminal connection line includes terminal connection lines connected to the pixel electrode pixel connection lines and terminal connection lines connected to the common electrode pixel connection lines,
• the terminal includes an image input terminal and a separated common electrode terminal, and
• at least a portion of the terminal connection line that is connected to one of the multiple common electrode pixel connection lines overlaps the terminal connection line that is connected to one of the multiple pixel electrode pixel connection lines via the insulation film.
