Not with the newer panels. Heck, I've got a Sharp TV--26'', couple of years old (though the model may be three or four years old.) Its viewing angle and picture quality is excellent.
Sharp is second only to Samsung in terms of quality and technology. Samsung gets the edge simply because they recently figured out a way to remove the LCD's color wheel, simultaneously increasing color vibrancy and reducing response times.
I've got a 50 inch Samsung and it was worth every penny, especially with Bose surround sound speakers.
