Embodiment Construction

[0042] Then, with regard to the embodiment of the present invention, it is described in detail with reference to the accompanying drawings:

[0043] FIG. 1 is a partial plan view of an organic electroluminescent display device according to a first embodiment of the present invention. figure 2 for this cross-sectional view. In Figure 1 and figure 2 in which with Figure 7 and Figure 8 For the same components, only the same symbols are added, and the description of this part is omitted.

[0044] The organic interlayer insulating films 216A and 216B are formed on the upper layer of the driving thin film transistor 204, and the drain of the driving thin film transistor 204 is connected to the anode of the organic electroluminescent element 203 through the contact hole provided in the organic interlayer insulating film 216B. . The organic interlayer insulating films 216A and 216B are formed of, for example, acryl resin.

[0045]The organic interlayer insulating films 216A a...

Abstract

Provided is an organic EL display which prevents infiltration of moisture into a picture element region and improves the reliability of the organic EL display. The picture element region (200) in which a plurality of picture elements are disposed in a matrix is formed on a device substrate (100), and each picture element of the picture element region (200) is provided with an organic EL device (203) and a driving transistor (204) to drive the device. Organic interlayer insulating films (216A, 216B) are formed on an upper layer of the driving transistor (204) but below a lower layer of the organic EL device (203). A sealing substrate (300) is adhered to the device substrate (100) via a sealing member (301) arranged on the peripheral region of the picture element region. The organic interlayer insulating films (216A, 216B) are divided by a dividing region (S) provided between the sealing member (301) and the picture element region (200).

Description

technical field [0001] The present invention relates to an organic electro-luminescent display device (Organic Electro-luminescent Display Device), in particular to arranging a plurality of pixels on a device substrate to form a pixel region (pixel region), and including an organic electro-luminescent element in each pixel, and for driving the organic An organic electroluminescent display device with a transistor for driving an electroluminescence element. Background technique [0002] In recent years, organic electroluminescent display devices using organic electroluminescent elements have attracted people's attention as display devices replacing cathode ray tubes (CRT) and liquid crystal displays (LCD). For example, the research and development of electroluminescent display devices equipped with thin film transistors (Thin Film Transistor, TFT) for switching elements (switching elements) to drive the organic electroluminescent elements are also being carried out in various...
