Flexible display panel, flexible display device, and method of fabricating flexible display panel

A flexible display panel, comprising:

• a flexible substrate;
• a display layer on the flexible substrate;
• and
• a lens layer and a color filter on the display layer;
• wherein:
• the display layer comprises a plurality of light-emitting units,
• the color filter layer comprises a black matrix that defines a plurality of filter units, each filter unit corresponding to one of the plurality of light-emitting units,
• the lens layer and the color filter are on a light-emitting side of the display layer,
• the lens layer comprising at least one lens, the at least one lens corresponding to at least one of the plurality of filter units, and
• the at least one lens is configured to magnify light emitted by a light-emitting unit into a magnified light spot, and project the magnified light spot onto a filter unit corresponding to the light-emitting unit, the magnified light spot having an area larger than a surface area of the corresponding filter unit in a non-stretched state, wherein an entirety of a light-emitting region of each of the plurality of light-emitting units is located within a focal length of the at least one lens.
