Display device with position input function

A display device with a position input function comprising:

• at least one pixel electrode;
• a common electrode disposed to at least partially overlap the at least one pixel electrode via an insulating film;
• position detection electrodes prepared by dividing the common electrode and configured so that a position input member for position input operation and corresponding one of the position detection electrodes form a capacitor to detect a position of input by the position input member;
• position detection lines disposed not to overlap the at least one pixel electrode such that at least the insulating film is disposed between the common electrode and the position detection lines and selectively connected to the position detection electrodes via contact holes formed at least in the insulating film;
• and
• a light blocking portion disposed to overlap at least a section of the at least one pixel electrode and including a pixel opening, the light blocking portion blocking light, wherein
• the common electrode includes openings overlapping at least sections of the position detection lines and including opening edges,
• the opening edges include first opening edges located closer to the at least one pixel electrode relative to the position detection lines and second opening edges located on an opposite side from the at least one pixel electrode relative to the position detection lines, and
• the first opening edges are closer to the position detection lines in comparison to the second opening edges,
• the first opening edges and the second opening edges of the openings in the common electrode do not overlap the position detection lines, and
• non-overlapping areas between the first opening edges and the position detection lines are smaller than non-overlapping areas between the second opening edges and the position detection lines.
