Abstract Provided is a liquid crystal display apparatus in which a viewing angle is increased, a front contrast is improved and a color shift, when viewed from an oblique direction, is prevented. A liquid crystal display apparatus (1) comprises a first light polarizer (2), a first optical compensation layer (3), a liquid crystal cell (4), a second optical compensation layer (5), and a second light polarizer (6), arranged in this order. The first and second optical compensation layers (3, 5) satisfy the following formulae (1) to (3), and the liquid crystal molecules in the liquid crystal cell (4) are oriented in the thickness direction of the liquid crystal cell (4) at a black display; n x 1 > nz1 > ny1 (1) nx 2 = ny2 > nz2 (2) DSP(Ro1) < 1 < DSP(Rth2) (3) La présente invention concerne un afficheur à cristaux liquides dans lequel l'angle de visualisation augmente, le contraste avant est amélioré, et la variation chromatique est empêchée lors d'une visualisation oblique. Un afficheur à cristaux liquides (1) comprend un premier polariseur de lumière (2), une première couche de compensation optique (3), une cellule de cristaux liquides (4), une seconde couche de compensation optique (5), et un second polariseur de lumière (6), agencés dans cet ordre. Les première et seconde couches de compensation optique (3, 5) satisfont aux formules (1) à (3) suivantes, et les molécules de cristaux liquides dans la cellule de cristaux liquides (4) sont orientées dans le sens de l'épaisseur de la cellule de cristaux liquides (4) au niveau d'un afficheur noir. N x 1 > nz1 > ny1 (1) N x 2 = ny2 > nz2 (2) DSP(Ro1) < 1 < DSP(Rth2) (3)
