Title: LIQUID CRYSTAL DISPLAY DEVICE
Abstract:
This liquid crystal display device (100) is provided with a liquid crystal display panel (1) that comprises a first substrate (10), a second substrate (20) and a liquid crystal layer (30). The first substrate comprises a first electrode (11), which is provided in each pixel, and a second electrode (12) that generates, together with the first electrode, a transverse electric field in the liquid crystal layer. The second substrate comprises a third electrode (21) which generates, together with the first electrode and the second electrode, a vertical electric field in the liquid crystal layer. In a state where a transverse electric field is generated in the liquid crystal layer, liquid crystal molecules (31) in the liquid crystal layer are twist-aligned. The thickness d of the liquid crystal layer and the natural chiral pitch p of the liquid crystal layer satisfy the relational expression 1 ≤ p/d ≤ 3. The dielectric anisotropy ∆ε of a liquid crystal material contained in the liquid crystal layer is from 16 to 25 (inclusive).
