Dell laptop screen cam apart

After two years of normal use, the screen on my Dell Inspiron has split. It seems that Dell quality has deteriorated, because my wife has had two Dells over the past 15 years, each with no problem. A friend in the trade said it was not properly glued or just cheap plastics, or both. It's sad to see another "American" company's quality get so bad. I sent photos to Dell, but they refused to help.
