A moving picture display apparatus comprises a main body and an external memory detachably mounted on the main body. The main body of the moving picture display apparatus is provided with a video data memory for storing therein graphic data of characters which constitute objects. A program data memory of the external memory has object data of an object to be displayed on a raster-scan type monitor, i.e., color pallet data, object name data, vertical position data, horizontal position data, object size selection data and size designation data and etc., all of which have previously been stored therein. Object data of an object to be displayed during the next vertical period is read from the program data memory so as to be stored in an object attribute memory. An inrange detection circuit makes a decision as to whether or not an object is in an inranged state, based on the vertical position data, the size selection data and the size designation data, and also makes a decision as to whether or not the object is in the inranged state, based on the vertical position data, the size selection data and the size designation data.
