Answer 1

You are returning $user->display_name;. You need to return $display_name. Try the below code.

function display_current_user_display_name () {
    $user = wp_get_current_user();
    $display_name = $user->user_login;
    return $display_name;
}
add_shortcode('current_user_display_name', 'display_current_user_display_name');

Answer 2

Shorter code:

function display_current_user_display_name () {
    $user = wp_get_current_user();
    return $user->user_login;
}
add_shortcode('current_user_display_name', 'display_current_user_display_name');
