Abstract

The purpose of the present invention is to obtain a display device which does not feel the presence of an LED device when the LED device does not emit light, has an excellent display effect when the LED device emits light, and has excellent designability and flexibility. Specifically, the display device includes: an LED device including a plurality of LED elements soldered to one surface side of a flexible substrate; and a non-porous material having a visible light transmittance of 5-80%, the non-porous material covering at least a portion of the LED arrangement surface side of the LED device.

Description

technical field [0001] The present invention relates to a display device including a flexible LED device and a non-porous material covering at least a part of an LED arrangement surface side of the LED device. Background technique [0002] LED display devices such as dot matrix display devices are rapidly spreading, and the LED display devices can display information such as arbitrary characters, symbols, and patterns by selectively emitting light from LED elements. [0003] Conventional LED display devices have widely used devices in which LED elements are mounted on a substantially inflexible rigid substrate. However, since the degree of freedom of design of such an LED display device is low, its use and the like are limited. [0004] As a flexible LED display device that can be formed into a target shape, for example, the devices listed in Patent Documents 1 and 2 are known. [0005] In Patent Document 1, it is described that it can be wound around a pillar or the like ...
