Create List item Sharepoint 2010 REST with Choice column

Question

I am trying to create one new list item in Sharepoint 2010 using REST.

Coding

var itemProperties = {
'Title': ;Raja;, //Single line String
'Expiry_x0020‌​_Date': "02/02/2016", //Date
'Permission_x0020‌​_Type': 'Add' //Choice Column
};

createListItemREST('http://xyz:5000/sites/n/', 'L2', itemProperties, function(task){ 
console.log('Task' + task.TaskName + ' has been created');}, function(error){ console.log(JSON.stringify(error)); });

function createListItemREST(webUrl,listName, itemProperties, success, failure) {
    $.ajax({
        url: webUrl + "/_vti_bin/listdata.svc/" + listName,
        type: "POST",
        processData: false,
        contentType: "application/json;odata=verbose",
        data: JSON.stringify(itemProperties),
        headers: {
            "Accept": "application/json;odata=verbose"
        },
        success: function (data) {
            success(data.d);
        },
        error: function (data) {
            failure(data.responseJSON.error);
        }
    });
}

i am getting following error.

400 Bad request

{"code":"","message":{"lang":"en-US","value":"Error processing request stream. The property name 'Expiry_x0020‌​_Date' specified for type 'Microsoft.SharePoint.DataService.L2Item' is not valid."}}

Note: When trying with only Title column this coding is working.
