Touch panel and method of manufacturing touch panel

A method of manufacturing a touch panel including:

• sensor electrodes including a first electrode and a second electrode crossing each other in a plan view;
• an interlayer insulating film insulating the first electrode and the second electrode from each other;
• lines each electrically connected with one of the sensor electrodes;
• a light-shielding portion overlying the lines in a plan view;
• and
• a planarizing film covering the light-shielding portion, the method comprising the steps of:
• patterning a first transparent conductive film to form a layer containing parts of the sensor electrodes;
• patterning a highly-conductive film having a lower electric resistance than the first transparent conductive film to form a layer containing the lines;
• patterning a light-shielding film to form a layer containing the light-shielding portion;
• and,
• after forming the layer containing the light-shielding portion, pattering an insulating film to form a layer containing the interlayer insulating film and the planarizing film,
• wherein the step of patterning a light-shielding film and the step of patterning an insulating film are performed between the step of pattering a first transparent conductive film and the step of patterning a highly-conductive film.
