Assignee: RESEARCH INSTITUTE OF INDUSTRIAL SCIENCE & TECHNOLOGY
Field: Semiconductors (Electrical engineering)
Classification: CPC H  G  Y | IPC G  H

Claim 0:
1. A filtering panel comprising:
a molding layer portion;
a pattern layer portion having an incident surface into which emission light emitted from a light source and visual line light transmitted to an observer enter and a receiving surface opposite to the incident surface, the incident surface having a lower incidence surface inclined toward a lower region based on a reference line horizontal to a ground and an upper incidence surface inclined toward the lower region based on the reference line, and
a filtering layer portion disposed on the lower incidence surface of the pattern layer portion on which the incident surface of the visual line light entering from the lower region below the reference line, horizontal to the ground, is disposed, having reflectivity of visible rays of the visual line light incident from the lower region greater than reflectivity of visible rays of light incident from an upper region above the reference line by specular reflection, and transmitting infrared rays of the visual line light,
wherein the filtering layer portion is formed of a resin including a reflective ball, which is a ferromagnetic material performing specular reflection on the visible rays, and formed by applying electromagnetic force to the resin coated in a molten state on the lower incidence surface, to be cured in a state disposed on an outer surface in which the reflective ball faces the molding layer portion.
