Abstract: A display apparatus includes a display panel having a front area and a side area, a main body supporting the display panel, an auxiliary member arranged inside the main body, and a semi-transmissive mirror arranged between the auxiliary member and the front area, wherein the side area of the display panel may be arranged inside the main body to face the semi-transmissive mirror. Since an image partially emitted from the display panel may be reflected toward the front area, auxiliary members such as a camera, an illumination sensor, and a proximity sensor may be arranged inside the main body (or below a display) to embody a full screen display, whereby a user's satisfaction may be enhanced and a manufacturing process may be simplified.

Abstract: Discussed is a color filter substrate and a display device having the same. The color filter substrate prevents color filter layers or color patterns from being lost or broken during a production process. The color filter substrate is formed by forming connection patterns in the edges of red (R), blue (B), and green (G) color filter layers and red (R), blue (B), and green G) color patterns. The connection patterns and color patterns are simultaneously formed with the color filter layers.
