Liquid crystal display device

A liquid crystal display device comprising:

• a display panel including a first main surface and a second main surface opposite to the first main surface;
• a first member disposed in the first main surface side of the display panel;
• a second member disposed between the first member and the display panel;
• a backlight unit disposed in the first main surface side of the display panel;
• and
• a cover member disposed in the second main surface side of the display panel, the cover member having a rigidity greater than that of the display panel, wherein
• a coefficient of thermal expansion of the second member is greater than that of the first member,
• the first member and the second member, due to the second member having a coefficient of thermal expansion greater than that of the first member, are deformed at a temperature of 70° C. so as to press the display panel at a temperature of 70° C.,
• a deformation of the cover member is less than deformations of the first member and the second member at a temperature of 70° C.,
• the second member and the cover member press the display panel so as to reduce a cell gap of the display panel at a temperature of 70° C.,
• the first member and the second member are not disposed in the second main surface side of the display panel, and
• the backlight unit is deformed at a temperature of 70° C. so as to press the display panel at a temperature of 70° C.
