Fly's-eye lens sheet having light-shielding layer, method for fabricating the same, transmissive screen, and rear projection image display device

A transmissive screen, comprising:

• a Fresnel lens sheet;
• and
• a fly's-eye lens sheet having a light-shielding layer,
• wherein the fly's-eye lens sheet having the light-shielding layer includes
• a fly's-eye lens sheet body provided with fly's-eye lenses on one principal surface thereof,
• the light-shielding layer provided on an other principal surface of the fly's-eye lens sheet body, and
• a photosensitive adhesive layer disposed between the fly's-eye lens sheet body and the light-shielding layer, the photosensitive adhesive layer having adhesive and non-adhesive patterns,
• wherein the light-shielding layer includes a light-shielding portion disposed on the adhesive pattern and transmitting portions disposed on the non-adhesive pattern for transmitting light transmitted through the fly's-eye lenses,
• the transmitting portions are located at positions corresponding to light-collecting parts of the fly's-eye lenses,
• the light-shielding portion contains carbon particles, a carbon content of the carbon particles being 45% to 65% by weight, and
• the transmitting portions have an X shape or a modified X shape.

A rear projection image display devices comprising:

• a projector;
• and
• a transmissive screen which transmits and displays an image projected from the projector,
• wherein the transmissive screen includes
• a Fresnel lens sheet;
• and
• a fly's-eye lens sheet having a light-shielding layer,
• wherein the fly's-eye lens sheet having the light-shielding layer includes
• a fly's-eye lens sheet body provided with fly's-eye lenses on one principal surface thereof,
• the light-shielding layer provided on an other principal surface of the fly's-eye lens sheet body, and
• a photosensitive adhesive layer disposed between the fly's-eye lens sheet body and the light-shielding layer, the photosensitive adhesive layer having adhesive and non-adhesive patterns,
• wherein the light-shielding layer includes a light-shielding portion disposed on the adhesive pattern and transmitting portions disposed on the non-adhesive pattern for transmitting light transmitted through the fly's-eye lenses,
• the transmitting portions are located at positions corresponding to light-collecting parts of the fly's-eye lenses,
• the light-shielding portion contains carbon particles, a carbon content of the carbon particles being 45% to 65% by weight, and
• the transmitting portions have an X shape or a modified X shape.
