The present invention is related to a hand-held display device including a hand-held host with a display module, a camera module and an endoscope. Among these, the camera module includes an optical lens group and a light-sensing module. And then the optical lens group and the light-sensing module are combined into one package by a clean technology. Moreover, the hand-held host and the camera module are assembled and electrically connected via a first coupling means. The camera module and the endoscope are connected via a second coupling means. According to the above of that, the present invention can avoid to make a shadow on an image of the display module, and the camera module can be replaceable and removable by a user.本發明為一種手持式顯示裝置，其包括一具有顯示模組之手持式主機、一鏡頭模組以及一硬管鏡，其中，該鏡頭模組包括一光學透鏡組以及一光感測模組，且光學透鏡組與光感測模組以無塵封裝方式結合為一體。進一步說明，該手持式主機以第一結合手段組裝並電性連接於該鏡頭模組，而該鏡頭模組以第二結合手段連接於該硬管鏡。因此，如上述本案之手持式顯示裝置具有避免顯示模組之影像產生陰影，以及鏡頭模組可被替換拆裝。
