Abstract: Discussed is a stereoscopic image display device, which acquires design parameters based on the same aperture ratio and the same back distance regarding a single barrier cell when displaying different numbers of views using the barrier cell. The barrier cell, which includes first and second substrates opposite to each other, first electrodes arranged at an interval on the first substrate, a second electrode formed on the second substrate, and a liquid crystal layer between the first and second substrates, is driven to display different numbers of views. Assuming that a region of the barrier cell corresponding to a small view number is one unit, the number of unit drive regions divided in one unit is defined by K/A (where, ‘A’ is an aperture ratio of the barrier cell, and ‘K’ is {large view number/small view number}*n (‘n’ is a natural number between 1 and the small view number).
