Problems solved by technology

There are problems of poor yield and high manufacturing cost in terms of quality
[0050] In addition, a photographic exposure device and various peeling devices are required, and various peeling liquids are required, so there is a problem of high equipment cost.
[0051] In the case of the method of forming the uneven pattern disclosed in Patent Document 4 (Japanese Unexamined Patent Application Publication No. 2-165093), there is a problem with the quality of the appearance without adding a clear uneven pattern, and there is also a problem with the operability due to the use of an organic solvent.

Abstract

To provide a display plate for a solar timepiece, having a solar cell; a display plate for a solar cell apparatus, used for a desktop calculator etc. using a solar cell; and a method of producing a display plate for a solar cell apparatus. The display plate for a solar cell apparatus has a solar cell on its lower surface side. The display plate is constructed from a light transmissive substrate, a light transmissive reflection plate provided on the lower surface side of the light transmissive substrate, and a decorative member provided on the upper surface side of the display plate. Further, the light transmissive substrate has a reflection surface provided on its lower surface side or reflection surfaces on its upper and lower surface sides, and the reflection surface or surfaces are each a prism reflection surface.

Description

technical field [0001] The present invention relates to, for example, a display panel for a solar watch having a solar cell, a display panel for a solar cell device for a desktop computer using a solar cell, and a method for manufacturing a display panel for a solar cell device. Background technique [0002] Conventionally, display panels for solar cell devices, such as display panels (dials) for solar timepieces with solar cells, are configured to transmit received light to activate the power generation function of solar cells provided on the lower surface side. [0003] In this case, since the display panel of a solar watch requires light transmission, plastic has been used in many cases. That is, in addition to obtaining light transmittance, plastics also have advantages such as low cost and easy decoration such as painting or printing. [0004] As a solar timepiece, as shown in the top view of Fig. 36, the solar cells used for portable timepieces such as wristwatches ar...
