PDF is displayed as an empty white box

Question

I have a project called "Project" and the PDF file is "file.pdf" located at Project/app/assets/file.pdf. I want to make a PDF on a page called "file.html" located at Project/app/views/static/file.html.

I wrote the following code, but everything that is displayed is an empty white box.

<embed src="../../assets/file.pdf" width="500" height="375" type='application/pdf'>

I am sure my browser cannot find the file. What can i do wrong?

UPDATE: I also tried it with the image placed in app/assets/images/Image.png, for example:

<embed src="../../assets/images/Image.png" width="500" height="375" type='image/png'>

but this is not displayed either.

UPDATE 2: Console Output:
