Problems solved by technology

However, since the mask is on the blocking member, the upper surface of the blocking member may be scratched (eg, cracks may be caused)
Thin film encapsulation structures may be defective due to uneven surfaces and thus flexible display devices may have reduced effective lifetime

Embodiment Construction

[0103] Hereinafter, embodiments will be explained in detail with reference to the accompanying drawings. In this disclosure, the term "substantially" includes completely, nearly completely, or in some applications and according to those skilled in the art, any significant degree. Furthermore, "formed, disposed or located on" can also mean "formed, disposed or located on". The term "connected" includes electrical connections.

[0104] figure 1 is a plan view illustrating a display device according to example embodiments.

[0105] refer to figure 1 , the display device 100 includes a display area 10 and a peripheral area 20 .

[0106] A display structure can be provided in the display area 10 . The display image can be displayed in the display area 10 through a display structure (for example, organic light emitting diode, liquid crystal, etc.). Wires (eg, scan lines, data lines, power supply voltage lines, etc.) may be disposed in the peripheral area 20 . Here, wires may ...

Abstract

A display device and a method of manufacturing the same are disclosed. In one aspect, the display device includes a substrate including a display region and a peripheral region. A first block member is in the peripheral region and surrounding display structures, the first block member having a first height. A second block member is spaced apart from the first block member in a first direction extending from the display region to the peripheral region, the second block member surrounding the first block member, the second block member having a second height that is greater than the first height. A first encapsulation layer is over the display structures, the first block member, and the second block member. A second encapsulation layer is over the first encapsulation layer, the second encapsulation layer overlapping at least a portion of the first block member in the depth dimension of the display device.

Description

technical field [0001] The described technology generally relates to display devices and methods of manufacturing display devices. Background technique [0002] Since a flat panel display (FPD) is light and thin compared to a cathode ray tube (CRT) display, the FPD is widely used for image display and video display in portable electronic devices. Typical examples of FPD technology are Liquid Crystal Display (LCD) and Organic Light Emitting Diode (OLED) displays. [0003] Recently, a flexible OLED display that can be bent or folded by including a lower substrate and an upper substrate made of a plastic-like flexible material has been developed. For example, the lower substrate may be formed of a flexible substrate, and the upper substrate may have a thin film encapsulation structure. In order to block the penetration of water or moisture, the thin film encapsulation structure may include at least one inorganic layer and at least one organic layer, and the inorganic layer an...
