。 A two-layer STN in which an STN-type compensating liquid crystal cell in which the liquid crystal is twisted in a direction opposite to the twist direction of the liquid crystal of the display liquid crystal cell is arranged on the light incidence side or the light emission side of the STN-type display liquid crystal cell. In the liquid crystal display element, the liquid crystal layer thickness d 1a of the non-display area between each pixel display area of the display liquid crystal cell is made smaller than the liquid crystal layer thickness d 1 of the pixel display area, and the retardation Δn of the compensation liquid crystal cell is 2 ,
d 2 is made smaller than the initial state retardation Δn 1 , d 1 of the pixel display area of the display liquid crystal cell by the retardation variation due to the application of the OFF bias electric field, and the retardation Δn 1a of the non-display area of the display liquid crystal cell is , d 1a are equal to retardations Δn 2 , d 2 of the compensation liquid crystal cell.
