Abstract:
1. A liquid crystal display device comprising a liquid crystal display panel in which a TFT substrate including a pixel having a pixel electrode and a TFT and a counter substrate including a color filter are bonded to each other with a sealant, liquid crystals are applied into the substrates, a lower polarizing plate is bonded to the TFT substrate, and an upper polarizing plate is bonded to the counter substrate, the liquid crystal display device further comprising a first substrate bonded to the upper polarizing plate of the liquid crystal display panel with UV resin, wherein the liquid crystal display panel is of IPS type, the liquid crystals are applied into the liquid crystal display panel by ODF, the TFT substrate has columnar spacers with an upper diameter of 4 μm to 8 μm, the counter substrate has an overcoat film with a thickness of 1 μm to 3 μm, and a columnar spacer area ratio×an upper diameter is 0.04 μm to 0.05 μm in the case where the columnar spacer area ratio is defined as (the total area of all the columnar spacers in contact with the counter substrate)/(an area of the display area).
