An assembled type of display apparatus has a base and a display body. The base has a plurality of positioning posts and a resilient latching member. The display body has an outer casing. The outer casing forms a plurality of first positioning and guiding holes and a plurality of second positioning and guiding holes in a circumferential face and a rear face thereof, respectively. When the circumferential face of the outer casing is connected to the base, each of the positioning posts is retained in the corresponding first positioning and guiding hole, and the resilient latching member latches onto the outer casing. When the rear face of the outer casing is connected to the base, each of the positioning posts is retained in the corresponding second positioning and guiding hole, and the resilient latching member latches onto the outer casing.
