</ul>

here is the script

<script type="text/javascript">
    $('#submit').click(function() {  

    var files = $("[type='file']")[0].files;

    console.log(files)

    var data = {
       'images[]' : files , 
       csrfmiddlewaretoken: '{{csrf_token}}'
      }

    $.ajax({
            type: "POST",
            url : "{% url 'data_entry' %}",
            data: data,
            success: function(data) {

You have to tell the Jquery don't process the files. And also I found the workaround to add file in data... hope this will help...

that Illegal invocation error is because ajax doesn't handle objects... that's why we serialize form before entering into ajax and now your case you directly inject the file object then the error.

var data = new FormData();
$.each(files, function(key, value)
{
    data.append(key, value);
});

And in ajax...

$.ajax({
    ....
    processData: false,
    ....
