A CF substrate (2) is designed such that at an area of a black matrix (22) that is closer to a TFT substrate (1), a counter electrode (24) does not cover at least a part of a first area that faces source lines (13). Consequently, even when a foreign matter (13a) attaches to the source line (13), it is possible to prevent the foreign matter (13a) from contacting the counter electrode (24). This allows realizing a display panel and a display device in which electric leakage between a line electrode and a counter electrode is prevented even when a foreign matter attaches to a line electrode and a counter electrode.
