Almost all laptops use transmissive screens. With these, the light only passes once through the liquid crystal - from back to front. In order to be able to see the screen the backlight must be much brighter than the light reflected from the front of the glass. Unfortunately, direct sunlight is very strong!
A very few laptops (for example the
NEC Versa Daylite) have a reflective screen. There is no backlight. Instead daylight passes from front to the back where it is reflected by a mirror and passes back the other way. The stronger the daylight the brighter the image but indoors the image looks dull and lifeless - particularly when it's on a shelf in a shop next to a transmissive screen.
There are also transflective screens which combine the worst of both worlds but I don't think these have found their way into laptops.
