Embodiment Construction

[0029] Reference will now be made in detail to the preferred embodiments of the invention, examples of which are illustrated in the accompanying drawings.

[0030] Figure 4 is a plan view illustrating an FPD device according to a preferred embodiment of the present invention. Figure 5 is along Figure 4 A cross-sectional view taken along line V-V.

[0031] The FPD device 100 includes an upper substrate 110 and a lower substrate 120 . In the case where the FPD device is an LCD device, the upper substrate 110 includes a first electrode 111 and color filters having R (red), G (green) and B (blue) pigments, and the lower substrate 120 includes a second electrode 121 and Switching element (i.e. TFT). The LC layer is sandwiched between two substrates 110 and 120 . The upper and lower substrates 110 and 120 are sealed with a sealant S. Referring to FIG. If the FPD device is an organic EL device, the upper substrate 110 includes a first electrode 111, and the second substrate ...

Abstract

A flat panel display device includes at least one display panel. The display panel includes a first substrate and a second substrate facing each other, and a sealant sealing the first substrate and the second substrate, wherein at least one of the first substrate and the second substrate has at least one protrusion portion formed on a portion of an inner surface thereof to adhere to the sealant.

Description

technical field [0001] The present invention relates to a flat display device, in particular to a flat display device comprising at least one display panel. Background technique [0002] Generally, a flat panel display device (FPD) includes a liquid crystal display (LCD) device, an organic EL (Electro Luminescence) device, and the like. Such an FPD device has the advantage of a wider display area compared to other conventional display devices such as cathode ray tubes. [0003] figure 1 is a cross-sectional view illustrating a conventional liquid crystal (LC) panel used in an LCD device. The FPD device is explained below focusing on the LCD device. [0004] like figure 1 As shown, the LC panel 10 includes an upper substrate 12 and a lower substrate 14 with an LC layer 16 sandwiched therebetween. The upper substrate 12 includes color filters having R (red), G (green), and B (blue) pigments. Lower substrate 14 includes thin film transistors (TFTs)...
