You shouldn't check 'Read only' on the dictionary entry itself.  Instead, you need to go to the related lists at the bottom of that form and add a new 'Dictionary override' record for the extended table you want the field to be read only for.  You should see the option on that form.  If that doesn't work, please post a screenshot of where you're trying to set the field read only.

then i opened related related list button of dictionary override click on new

Here it is showing read only but i want read only in another table also for that what i do

You need to add a new dictonary override for each extended table just like you did for this one.
