  The present invention relates to a stereoscopic image display device and a manufacturing method thereof, and more particularly, to a stereoscopic image display device and a manufacturing method thereof that can improve the aperture ratio and luminance of the display device while reducing the width of a black matrix and facilitate the manufacturing process. .

  The stereoscopic image display apparatus realizes a stereoscopic image using a binocular parallax scheme or an autostereoscopic technique.

  The binocular parallax method uses parallax images of the left and right eyes with a large stereoscopic effect, and there are a spectacle method and a no-glasses method. In the eyeglass method, a three-dimensional image is realized using polarized glasses or liquid crystal shutter glasses by changing the polarization direction of the left and right time-difference images on a direct-view display element or projector or by using a time-division method.

The color filter 135 serves to convert light emitted from the backlight unit and transmitted through the liquid crystal layer 150 into red, green, and blue. In the color filter 135, the black matrix 130 is located, and serves to separate the left eye image and the right eye image. The overcoat layer 140 serves to protect the color filter 135 by reducing the level difference of the color filter 135.

The second retard pattern 180b is disposed to face the line on the display panel (DP) where the right eye image is displayed, and converts the light of the right eye image into the second polarized light (circularly polarized light or linearly polarized light).

  The first black stripe 165 is formed at a position corresponding to the black matrix 130. Here, in order to prevent the aperture ratio of the display device from being lowered, the width of the first black stripe 165 is formed to be narrower or the same as the width of the black matrix 130, and the black matrix is within a region corresponding to the black matrix 130. The area is smaller than or equal to 130.

For example, the binder may be one or more selected from an acrylic resin, a polyimide resin, a phenol resin, and a cardo type resin. These resins can be compounds containing acid groups or epoxy groups. Desirably, an epoxy acrylate resin can be used.

  The polyfunctional monomer is a compound that can be polymerized by a photoinitiator and can be an acrylate monomer. For example, ethylene glycol dimethacrylate (1, 4-cyclohexanediol acrylate, trimethylol triacrylate, trimethylolpropane triacrylate), pentaerythritol triacrylate (1,4-cyclohexanediol acrylate, trimethylol triacrylate) pentaerythritoltriacrylate, tetraethyleneglycoldiacrylate, depentaerythritoltriacrylate, dipentaerythritoltetraacrylate, sorbitoltriacrylate, sorbitoltriacrylate, sorbitoltetraacrylate, vinyl acetate, and triaryl cyanurate can be used.
