Horizontal alignment-type liquid crystal display device

A horizontal alignment-type liquid crystal display device in an in-plane switching mode comprising:

• a viewing-side polarizing plate;
• a liquid crystal cell;
• a backlight-side polarizing plate;
• and
• a backlight, in this order,
• wherein the liquid crystal cell includes a liquid crystal layer held between two substrates,
• wherein at least any one of the substrates is a polyimide resin substrate,
• wherein at least one of the viewing-side polarizing plate or the backlight-side polarizing plate provided on the polyimide resin substrate side includes a gas barrier film including a phase difference layer and an inorganic layer, and a polarizer,
• wherein the gas barrier film is on the polyimide resin substrate side with respect to the polarizer,
• wherein retardation of the polyimide resin substrate in a thickness direction at a wavelength 550 nm is 50 nm or greater,
• wherein in-plane retardation of the polyimide resin substrate at a wavelength of 550 nm is −10 nm to 10 nm,
• wherein a first phase difference layer satisfying nz≥nx>ny is included as the phase difference layer,
• wherein a slow axis of the first phase difference layer is parallel to an absorption axis of the polarizer, and
• wherein a second phase difference layer satisfying any one of nz>nx=ny or nx=ny>nz is further included as the phase difference layer.
