Display device and its manufacturing method, pattern displaying method, and blind device and blind method

Abstract

This display device (10) is comprised of a light guide plate (1) and a light source (6) provided on an end surface (1a) side of the light guide plate (1). A display unit (3) provided with a dot-like reflecting unit (2) with a reflective surface (2a) for reflecting light projected from the light source (6) to a surface (1b) side is formed on the light guide plate (1). The display unit (3) is set for the reflecting light from the dot-like reflecting unit (2) to be visually recognizable. The display device (10) is good at transparency and readily visually recognized, and can be easily manufactured at a low cost.

Description

technical field [0001] The present invention relates to a display device used for a display or the like, a method of manufacturing the same, a pattern display method using the display device, and a shielding device and a shielding method using the display device. [0002] This application claims priority based on Japanese Patent Application No. 2006-117238 filed in Japan on April 20, 2006 and Japanese Patent Application No. 2007-052910 filed in Japan on March 2, 2007, and uses the contents thereof. Background technique [0003] In recent years, opportunities for LEDs (light-emitting diodes) to be used in various applications as high-efficiency, long-life light sources are increasing. [0004] LED is a directional point light source. Since its use as spot lighting alone is limited, it is mostly used in combination with light guide plates such as transparent resin plates as a linear or planar light source. For example, LCD backlights, advertising light panels, etc. [0005] ...

AI Technical Summary

Problems solved by technology

[0010] However, when the area of ​​the display part, which is the opaque part, is large, the background cannot be seen through, and the transparency which is a characteristic of the display device is lost, thereby reducing its value.

[0011] In a display device in which LED elements are placed between transparent glass plates, only the LED elements block the transmitted light, so the transparency is better than the above-mentioned devices, but the electrode wiring pattern becomes complicated, resulting in very difficult manufacturing. difficult and expensive

[0012] In addition, unlike a display device in which a light source and a light guide plate are provided separately, in order to change the appearance of the display part, it is necessary to replace the entire unit including the light source (LED element).
