BTW Random he didn't told any thing wrong.You just think for a while..previous xperia phones where better in " display "
Only in display then 2013 xperias.. Whats wrong in that?
Then I must be blind, and also GSMArena and every other review site. Because 2012 Xperias also had poor viewing angles. The only Xperia with good viewing angles is the Z Ultra.
In terms of quality, 2013 displays are NOT inferior to 2012.
In case of Z/ZL it was more of a software issue, you can go and check a Z with latest firmware.
Xperia V -
In reality, viewing the screen head on will leave you pleased but as soon as you tilt the device to the side even slightly, the colors begin to look washed out and contrast is heading south at a frightful pace.

Xperia T - Sadly, Sony is yet to address the issue of poor viewing angles. You really need to be looking at the Xperia T head-on to experience arguably the best image quality from an LCD, as once you tilt the phone even a tiny bit, the image quality deteriorates noticeably.

Xperia S - Its only downside (and it's not a minor one) are the sub-par viewing angles.

And Xperia Z - However, the screen is by no means perfect.
First of all its viewing angles aren't really great. They are a step forward compared to the Xperia T, but a very minor one. In that area Sony still has a lot of work before it catches up with the competition.
