In this way, there will be no offset problem between the first lens body and the micro light emitting diode, and the light emitted from the micro light emitting diode will pass through the first lens body and be evenly directed to the liquid crystal panel, thereby improving The display quality of the electronic device.

（2）第一透鏡體可包含複數個光學粒子，光學粒子均勻地分布於第一透鏡體內，以調整光線經過第一透鏡體後的均勻度。(2) The first lens body may include a plurality of optical particles, and the optical particles are evenly distributed in the first lens body to adjust the uniformity of light after passing through the first lens body.

（3）第二透鏡體可根據實際狀況而設定為凹透鏡之形狀或凸透鏡之形狀，從而提升電子裝置的顯示品質。(3) The second lens body can be set to the shape of a concave lens or a convex lens according to the actual situation, so as to improve the display quality of the electronic device.
