Display panel

A display panel comprising:

• a planar decoration member comprising a shading part and a light transmission part formed within the shading part, the shading part and the light transmission part creating a fine pattern in a plan view;
• and
• a planar reflection member disposed on a back side of the decoration member, the reflection member being configured to reflect light;
• wherein the decoration member is adhered to a front surface of the planar reflection member by adhesive,
• wherein a front surface of the decoration member is a non-adhesive area in which no adhesive is impregnated,
• wherein the reflection member has a light transmittance,
• wherein the display panel is applied to a timepiece, the timepiece comprising a solar cell disposed on a back side of the reflection member,
• wherein the reflection member is pressed onto a plurality of micro projections formed on a light receiving surface of the solar cell, and
• wherein the reflection member has temperature characteristics such that the reflection member softens and contours shapes of the micro projections that are transferred onto the back surface of the reflection member under an environment of a predetermined temperature or higher.
