Abstract:
1. A liquid crystal display device comprising: a first substrate; a second substrate which is arranged to face the first substrate in an opposed manner; a sealing material which adheres the first substrate and the second substrate to each other; and liquid crystal which is sandwiched between the first substrate and the second substrate; wherein the first substrate includes: pixel electrodes which are formed inside a display region; an orientation film which is formed at a position where the orientation film is brought into contact with the liquid crystal; a plurality of projections which is formed of a first insulation film below the orientation film in a region inside the sealing material and outside the display region; a second insulation film which is arranged at a position where the second insulation film overlaps the plurality of projections and below the first insulation film, and is formed of a material to be etched by an etching gas which forms the first insulation film into the plurality of projections; and a first stopper layer which is formed at a position where the first stopper layer overlaps the plurality of projections and between the first insulation film and the second insulation film, the first stopper layer being formed of a material which possesses etching selection property for the etching gas and protecting the second insulation film from the etching gas, and assuming a width of the sealing material as W
