证据开示在诉讼中属于庭审前程序，是源于英美法系的概念，在我国又被翻译成证据展示、证据先悉、证据告知、证据公开等。证据开示的基本涵义是当事人双方互相出示案件有关信息；在我国刑事诉讼中，证据开示应指提起公诉后，开庭审判前，公诉人和辩护律师之间互相出示公诉案件? Evidence discovery belongs to pretrial procedure in litigation. It originated from the concept of Anglo-American legal system and has been translated into evidence display, evidence prior disclosure, evidence disclosure and evidence disclosure in our country. The basic meaning of evidence disclosure is that both parties show each other the relevant information about the case. In our country’s criminal proceedings, the evidence discovery should refer to prosecution cases between prosecutors and defense lawyers after prosecution.
