         10 . The display apparatus according to  claim 1 , wherein the controller comprises a setup screen storage, and the control screen and the plurality of reference screens are previously stored in the setup screen storage. 
     
     
         11 . The display apparatus according to  claim 10 , wherein the setup screen storage comprises an EEPROM or a flash memory. 
     
     
         12 . The display apparatus according to  claim 1 , wherein the reference screens comprise pictures such that the user easily distinguishes the different values of the picture display state. 
     
     
         13 . The display apparatus according to  claim 1 , wherein the reference screens are provided corresponding to each of the possible different values of the picture display state. 
     
     
         14 . The display apparatus according to  claim 1 , wherein each of the reference screens displays different picture display state values of a same picture. 
     
     
         15 . The display apparatus according to  claim 1 , wherein the picture display state is color, contrast, or brightness. 
     
     
         16 . A display apparatus comprising:
 a display; and   a controller to control a picture display state of a picture on the display by varying property values of the pictures based on a user's input;   wherein a control screen is displayed with a plurality of reference screens displaying different values of the picture display state, so that the user sees the different values of the picture display state that are available,   wherein the reference screens are invariable screens displaying different values of the picture display state, and the control screen is a variable screen varying according to manipulation by the user.   
     
     
         17 . A display apparatus comprising:
 a display screen which displays a control screen and a plurality of reference screens; and   a controller which controls the display screen to display an indicator which is operable to adjust a value of a property of a picture, controls the control screen to display the picture according to the current value of the property of the picture, and controls the display screen to display the control screen concurrently with the plurality of reference screens,   wherein each reference screen is invariable and each reference screen displays the picture according to a different reference value of the property of the picture, and   wherein the displaying of the picture in the control screen varies according to an operation of the indicator adjusting the current value of the property of the picture.   
     
     
         18 . The display apparatus according to  claim 17 , wherein the indicator includes a control bar which shows a range corresponding to values which can be selected by a user. 
     
     
         19 . The display apparatus according to  claim 17 , wherein the indicator includes a current value. 
     
     
         20 . A display apparatus comprising:
