No.  Nothing is leaking out.  The appearance looks like water streak going across the top of the screen.  It is transparent.  In the upper left corner the area is somewhat larger, but thru the middle (at the very top of the screen ) it is about a quarter inch wide.  Every day when I sign on, it has expanded further to the right about an inch or two.  

in that case if it were a touch screen panel this phenomenon would be called delamination and is an unfortunate defect of touch screen

Thank you for your assistance.  It is an older computer

upload a pic if you can.

It has now moved completely across the screen.  It's an all-in-one PC.   Is there anything I can do?  Will it eventually obliterate the screen image.  I have a picture...how to download? 

it may be touchscreen delamination.  the entire screen needs to be replaced, but since it is old pc, not worth the cost.

If I let it go for a while, will it be okay.  This is bad time of year financially for me to have buy another PC :(  

if it is delamination it either stays bad or gets worse but would not reverse damage.
