Abstract
The disclosure provides a stereoscopic image display device, including: multiple display units, the multiple display units being arranged in rows and columns, a first black matrix being disposed between adjacent rows of display units, and a second black matrix being disposed between adjacent columns of display units. The stereoscopic image display device also includes a lens sheet disposed corresponding to the multiple display units, the lens sheet being formed by multiple lined up half-cylinder lenses, and, in an X-direction, a cycle length of the half-cylinder lenses in the lens sheet being a positive even multiple of a cycle length of the display units. In the display device, X coordinate values of the multiple display units do not repeat periodically within one cycle of the lens sheet. The stereoscopic image display device according to the disclosure can solve a problem of black and white stripes, thereby improving the display effect.
