You could write a custom LabelFor helper which doesn't HTML encode the text as does the standard LabelFor helper:

public static class LabelExtensions
{
    public static IHtmlString UnencodedLabelFor<TModel, TProperty>(this HtmlHelper<TModel> html, Expression<Func<TModel, TProperty>> expression)
    {
        var metadata = ModelMetadata.FromLambdaExpression(expression, html.ViewData);
        var htmlFieldName = ExpressionHelper.GetExpressionText(expression);
        var text = (metadata.DisplayName ?? (metadata.PropertyName ?? htmlFieldName.Split(new char[] { '.' }).Last<string>()));
        if (string.IsNullOrEmpty(text))
        {
            return MvcHtmlString.Empty;
        }
        var tagBuilder = new TagBuilder("label");
        tagBuilder.Attributes.Add("for", TagBuilder.CreateSanitizedId(html.ViewContext.ViewData.TemplateInfo.GetFullHtmlFieldName(htmlFieldName)));
        tagBuilder.InnerHtml = text;
        return new HtmlString(tagBuilder.ToString(TagRenderMode.Normal));
    }
}

and then use this custom helper in the view:

@Html.UnencodedLabelFor(x => x.IsLimitedQuantity)

Now the HTML tags in the display name will be rendered without encoding:

[Display(Name = "Check to enter <br/> the Quantity of items")]
public bool IsLimitedQuantity { get; set; }

Using Html decode may help. MVC for security reasons encode all the values.
