Method of manufacturing active matrix substrate and liquid crystal display device

A liquid crystal display device comprising:

• an active matrix substrate provided with a plurality of thin film transistors corresponding to a plurality of subpixels;
• a counter substrate facing the active matrix substrate;
• and
• a liquid crystal layer provided between the active matrix substrate and the counter substrate,
• wherein the active matrix substrate includes:
• color filters with colored layers having predetermined colors disposed on the plurality of thin film transistors, respectively,
• antireflection layers overlapping boundary portions of the colored layers, each of the antireflection layers including a metal layer and an inorganic insulating layer layered,
• a first transparent electrode, a second transparent electrode, and a third transparent electrode provided above the color filters in a stated order in which the first transparent electrode, the second transparent electrode, and the third transparent electrode are increasingly separated from the color filters, and
• an inorganic protection film made of an inorganic insulating film provided between the first transparent electrode and the second transparent electrode,
• the antireflection layers are provided on the second transparent electrode,
• the third transparent electrode is in contact with the second transparent electrode at least in the plurality of subpixels, and
• the second transparent electrode is provided between the inorganic protection film and the antireflection layers.
