ListaEstadoCuenta is a List. This means you have to specify the item in the bindings of your Labels. E.g. for the first Item:

<ViewCell>
<!-- ... -->
    <Label Text="{Binding ListaEstadoCuenta[0].Comprobante}" />
    <Label Text="{Binding ListaEstadoCuenta[0].FechaDoc}" />
<!-- ... -->
</ViewCell>

If you want to show list items in one Label, you have to use Converters to combine the values:

Value converter

public class StringConcatenationConverter : IValueConverter
{
    public object Convert(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture)
    {
        if (value is IEnumerable<EstadoCuentaDetalle>)
        {

            return string.Join(", ", ((IEnumerable<EstadoCuentaDetalle>)value).Select(x => x.Combrobante));
        }
        return value;
    }

    public object ConvertBack(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture)
    {
        throw new NotImplementedException();
    }
}

Resource in your Page

You have to adjust the local namespace xmlns:local to refer your assembly name.

<ContentPage ...
             xmlns:local="clr-namespace:FormsTest;assembly=FormsTest">
  <ContentPage.Resources>
    <ResourceDictionary>
      <local:StringConcatenationConverter x:Key="concatConverter"></local:StringConcatenationConverter>
    </ResourceDictionary>
  </ContentPage.Resources>

Binding

<Label Text="{Binding ListaEstadoCuenta, Converter={x:StaticResource Key=concatConverter}}" />
