How important is the thesis document for judges on the day of the thesis defense? I want to defend my thesis in the computer networking field on master degree . all things are done. And now I want to write my thesis document. Is this document important for judges in the defend day or not to evaluate my thesis.

I ask this question because I think they just pay attention to your suggested method and result and presentation. 

Is the document are so important for them? because if they do not pay a lot attention to that I do not like take a lot of effort on that maybe you say that I can put that on the internet for any citation By our language is not English.

If the answer is yes. I mean they pay attention to the document in case of evaluating my thesis. What parameter are important for them. Or better to say, I should bold which part or how to write my thesis in order to the judges pay attention to that? and they say themselves this student try hard and I should give him good score ( D: )
Is this document important for judges?


You are really asking the wrong question. Any official document that bears your name eternally is important for you and your future. You are a MSc student with probably small number of publications (if any) and a MSc thesis is an important milestone on your transition from a student to a researcher. It is also a quite large document (much larger than the typical scientific publication), so writing an excellent document at this scale is a valuable lesson even if you want to work in industry, where technical reports / documentation and deliverables are quite common. 

Conclusively, you must always strive for excellence and always do the best you can. You must change your student mindset from "Would doing A would get me a better grade" to the adult mindset "Is this really the best I can do within the time constraints I have or could I do better?". So you should focus on producing the best thesis document you can (within your time constraints)  regardless of how lenient the committee might be on judging it.
