1988 was the first LCD TV, it was 14 inches. It was awful but it was a TV. Pretty sure the first active-matrix laptop was also 1988 with the Macintosh Portable, which didn't even have a backlight and was monochrome. None of the stuff that came before.
According to this, 1989 was the first year 10-inch TFT LCD monitors existed: http://www.personal.kent.edu/~mgu/LCD/index.htm
I feel pretty good about arguing 1988 was the first real year of commercialization of LCD as we understand it today. I'm also comfortable with using the 2002 date as the analogue to what we are talking about with PDP and OLED. Referring to passive matrix laptops or worse laptops with some cash-register sized LCD display as comparable confusing things. By that logic, there was a digital camera with an OLED in 2000. And a monochrome plasma in 1983 with a full-color monitor-sized one in 1992.
If we're compared apples to apples, we should just ignore the 14-inch LCD TV milestone entirely and stick with 2002. The only reason I mentioned the 1988 TV was that it technically qualifies as "commercialization of a television." That's also analogous to the milestones I listed for PDP and OLED, even though it was a tiny LCD TV. The early laptop computers are not remotely similar in that regard.
