Abstract
A reflective type screen using a spacer layer and that includes a light blocking layer blocking an incident light, a reflective layer formed on the light blocking layer to reflect the incident light, a diffusion layer formed on the reflective layer to diffuse the incident light, and at least one spacer layer formed between the reflective layer and the diffusion layer to have a refractive index differing from that of an adjacent layer to refract the incident light.
Claims20
A reflective type screen, comprising:
- a light blocking layer configured to block an incident light;
- a reflective layer formed on the light blocking layer and configured to reflect the incident light;
- a diffusion layer formed on the reflective layer and configured to diffuse the incident light;
- and
- at least one spacer layer formed between the reflective layer and the diffusion layer and configured to have a refractive index differing from a refractive index of an adjacent layer.

A reflective type screen, comprising:
- a light blocking layer configured to block an incident light;
- a reflective layer formed on the light blocking layer and configured to reflect the incident light;
- first and second diffusion layers formed on the reflective layer and configured to diffuse the incident light;
- and
- at least one spacer layer formed between the first and second diffusion layers and having a refractive index differing from a refractive index each of the first and second diffusion layers.
