The present invention is an optical fiber holder and ball length direction through penetrating to one side one and the other sides toward and diameter is formed in a tapered shape to be small can be an optical fiber is passed through the other side in a light emitting display using the provided and this the outer peripheral surface fitted in a tapered shape in which a portion corresponding to the outer peripheral surface shape of the first holder so as to press the outer circumferential surface of the first holder to be fitted with the first holder provided with a coupling protrusion protruding in a radial direction, wherein the first holder groove is provided and the optical fiber which is drawn is formed from the inner peripheral surface of the mounting recess in a radial direction passing through the with the body part the inlet groove fitting projection and the coupling provided, the body parts of the one side end extends being inside the first holder in the is passed to a second holder including a hollow head portion which is communicated with the mounting grooves provided.
According to this optical fiber holder, there is an advantage that the working time can be shortened to facilitate the installation and removal of the optical fiber to the base plate. In addition, since the first holder and the second holder in the structure for fixing the optical fibers into the optical fiber 2 to prevent departure from the base plate it has the advantage to increase the operability and visibility of the light-emitting display device.
