Display panel, display device, and method for manufacturing display panel

A method for producing a display panel,

• the display panel including
• a first substrate having a surface provided with an electrode layer,
• a second substrate having a surface provided with line routing for applying signals to the electrode layer, the surface of the second substrate facing the surface of the first substrate,
• a sealing section defining a sealed space between the opposing surfaces of the first and second substrates, and
• a plurality of pillar sections enabling electrical connection between the electrode layer and the line routing,
• the method comprising:
• providing a plurality of coloring films one by one on the surface of the first substrate to obtain a base including the plurality of coloring films stacked on one another,
• forming the pillar sections on the surface of the first substrate and then forming the sealing section on the surface of the first substrate at a position where the sealing section is not in contact with the pillar sections;
• causing the surface of the first substrate and the surface of the second substrate to face each other;
• and
• bonding the first substrate and the second substrate together through the sealing section to electrically connect the pillar sections to the line routing on the second substrate, wherein
• the position at which the sealing section is formed allows the sealing section spreading due to the first and second substrates being bonded together through the sealing section to be in contact with the pillar sections,
• each of the pillar sections includes the base and the electrode layer covering the base, the base including the plurality of coloring films stacked on one another on the surface of the first substrate at a position that allows the pillar section to be in contact with the sealing section, and
• in the base, each of the plurality of coloring films is in contact with the surface of the first substrate, and among the plurality of coloring films, a first coloring film is entirely covered by a second coloring film provided immediately after the first coloring film.
