And I must respectfully disagree with Kurt.
My understanding is that there is no liquid in a Liquid Crystal video display; and certainly no WATER which could freeze. My understanding is that LCD's are just like Plasma video displays in that they contain crystalline solids that change their crystalline structure very rapidly when a voltage is applied to them, making that material either opaque or transparent. This is why plasma displays like you see on car stereos or even on the car dashboard will always have a coloured background and segments which are either black or very transparent (so that they're darn near invisible).
Samsung says that their LCD TVs can be stored safely at temperatures between -4 F to 113 F or -20 C to 45 C.

And, it says that storing their LCD TV's at temperatures above or below that range "can" damage the TV set, not "will" damage the TV set, so you've got some wiggle room on each side of that range.
And that kinda makes sense when you consider that lots of cars have LCD video displays on the back of the front seat headrests so that the kids in the back seat can watch TV so they don't get bored and start kicking the back of the seats dad and mom are sitting in. And, those cars are parked outdoors here in Canada in places like Yellow Knife in the North West Territories where -40 C to -50 C temperatures are not uncommon in winter. Also, lots of police cars have laptop computers in them with LCD displays so the cop can check a car's license number to make sure it's not stolen or check for any warrents for the person driving that car, and those police cars can be parked at a crime scene for long enough that the interior of the car gets very cold. GPS systems in cars also use LCD video displays just like laptop computers.
But, if you do keep your LCD TV outdoors, you want to anchor it down some way so that the wind doesn't knock it over or it get stolen. You also want to cover it to keep the rain or snow melt out of it, and to shade it from intense sunlight during the summer . Also, if you bring it indoors during the winter, you want to give it a few days to warm up to room temperature before plugging it in or turning it on. That's because condensation forming on the cold circuit boards inside the TV might cause electrical shorts which could wreck the electronics on those boards. And, you want to wait long enough so that not only do those circuit boards warm up to normal operating temperature, but any condensation that might have formed on them also evaporates.
So, I expect that if you use your common sense, and you don't live where outdoor temperatures don't fall too far below -4 F or too much above 113 F, then you can safely store your LCD TV outdoors. But store it so that it's out of the Sun, out of the wind, covered so that rain or snow melt can't get into the TV and anchored down so that it can't be stolen.
