Displays dates less than the current day's date

Question

In my program, I have a data grid view. I make some amounts due for payment today. I made a display of the amounts that are due and have not been paid (late) I want a code that displays the dates less than the current date of the day I tried that following code but it only fetches the lower days and does not look For the month or year if it is greater or not than the current day's date

        tbl = db.readData("SELECT  * from Payments  where date_batch < CONVERT(varchar(50),GetDate(), 103)", "");
        DgvSearch.DataSource = tbl;

The problem with the previous code is that it doesn't fetch the date lower by day, month and year. Fetches the date less than the current date in terms of day only I want in terms of day, month and year
