- a functional optical layer well known in the art for improving the optical function of the stereoscopic image display apparatus such as a brightness enhancement film in addition to the above configurations.
- the method for manufacturing a stereoscopic image display device includes (a) applying a phase change ink composition to an upper portion of an image generating portion or a lower portion of a 3D filter layer to a position corresponding to a boundary between a first region and a second region of the 3D filter layer. Forming a light shielding pattern; (b) laminating a 3D filter layer on the image generator and (c) irradiating an active energy ray to cure the light shielding pattern.
- a phase change ink composition is applied to an upper portion of an image generator or a lower portion of a 3D filter layer to form a light shielding pattern at a position corresponding to a boundary between a first region and a second region of the 3D filter layer.
- the applied phase change ink composition is applied in a liquid state, and rapidly solidifies due to a low temperature of the surroundings to form a pattern.
- the light shielding pattern is positioned corresponding to the boundary between the first region and the second region of the 3D filter layer.
- the coating may be carried out through a method of applying a phase change ink well known in the art, for example, inkjet printing.
- the phase change ink composition must be in a liquid state in order to apply the coating is preferably carried out at a temperature above the melting point of the phase change ink composition. More specifically, the coating is preferably performed at Tb °C to (Tb + 100) °C when the melting point of the phase change ink composition is Tb. This is because when applied in such a temperature range, the phase change ink composition can be applied in a liquid state and can be solidified immediately in the process of being applied and contacted onto the substrate. If the application is performed at a temperature lower than Tb ° C., the phase change ink composition may remain in a solid state without being completely dissolved, thereby blocking the exit of the application device.
- the coating is preferably carried out at a temperature of 50 °C to 160 °C, for example, may be carried out at a temperature of 60 °C to 140 °C, 80 °C to 125 °C.
- the temperature to be applied varies depending on the melting point of the phase change ink composition, the type of device to be applied, and the like, but in consideration of the cost advantage of the equipment, a temperature of 50 ° C to 160 ° C is preferable.
- the melting point of the phase change ink composition is higher than the temperature of normal temperature, so that heat is taken away from the ambient temperature in the process of being applied onto the substrate, Lowered to temperature and solidified. Therefore, when the light shielding pattern is formed using the phase change ink composition as in the present invention, the phenomenon of droplet spreading on the substrate can be controlled without considering the surface energy-surface tension of the substrate to be applied, thereby preventing the conventional problem. I can solve it.

- the step of pressing the light shielding pattern may be further performed after any one of the steps (a) and (b).
- the pressing step is preferably performed at (Tb-20) ° C. to (Tb + 15) ° C. when the melting point of the phase change ink composition is Tb, for example, (Tb-15). It may be carried out at) °C to (Tb + 10) °C or (Tb-10) °C to (Tb + 5) °C.

Also in this case, the present invention is not limited to the above manner, and may be performed by various methods well known in the art.
- the relative speed of the substrate and the pressing roll formed with the light shielding pattern is preferably performed at a traveling speed of about 1 to 150m / s, for example, It may be performed at a running speed of about 3 to 140 m / s and about 5 to 130 m / s.
- the relative speed is independent of the time to press, and is related to the process speed of the pattern forming process, and as the process speed increases, the substrate may have fine vibrations up and down, and thus control of the relative speed is necessary.
- the pressing step is another example that is performed by the flat plate, it can be pressed using the flat plate in a direction opposite to the substrate surface on which the pattern is formed.
- the pressing may be performed in a state in which a protective film, a release film, or other film is attached or laminated on the light blocking pattern, but is not limited thereto.
- the phase change ink composition When the phase change ink composition is pressed in a state where it is not completely solidified, the phase change ink composition may be adhered to the pressurizing device and the shape of the light shielding pattern may be collapsed. This is because a defect may be caused in the formation process.
- the phase change ink composition may be prevented from adhering to the pressurizing device, and defects may be minimized even in a continuous process.
- the method of manufacturing a stereoscopic image display device of the present invention includes the step of (c) irradiating an active energy ray to cure the light shielding pattern.
- Step (c) is to fix the light shielding pattern.
