Embodiment Construction

[0042] Organic EL device

[0043] First, as an embodiment of the present invention, the figure 1 The organic EL device (electro-optical device) 100 shown will be described.

[0044] The organic EL device 100 is a self-luminous display device shown as an example of an "electro-optical device" in the present invention. also, figure 1 It is a plan view schematically showing the structure of the organic EL device 100 .

[0045] Such as figure 1 As shown, the organic EL device 100 has an element substrate 10 and a sealing substrate (protective substrate) 70 . The element substrate 10 and the sealing substrate 70 are bonded by an adhesive (not shown) in a state of facing each other. In addition, as an adhesive, epoxy resin, acrylic resin, etc. can be used, for example.

[0046] The element substrate 10 has a sub-pixel 20B in which an organic EL element (light-emitting element) 30B generating blue (B) light is arranged, a sub-pixel 20G in which an organic EL element 30G generat...

Abstract

The present invention relates to an electro-optical device and electronic equipment. The electro-optical device includes: an element substrate including a display area in which a plurality of light-emitting elements are arranged in a matrix; and a terminal area in which mounting terminals are arranged outside the display area; a substrate facing the plurality of light-emitting element sides of the element substrate; and a bonding substrate bonded to the terminal region of the element substrate and having connection terminals. On the element substrate, a sealing film for sealing the plurality of light emitting elements is also formed in the terminal region. The mounting terminal is connected to the connecting terminal. In the electro-optical device, there is a portion where the sealing film is removed and bonded to the bonding substrate.

Description

technical field [0001] The present invention relates to electro-optical devices and electronic equipment. Background technique [0002] As an example of an electro-optical device, an organic EL device is proposed in which pixels using organic electroluminescence (EL: Electro Luminescence) elements are arranged in a matrix in a display region of an element substrate (for example, refer to Patent Document 1). [0003] Specifically, Patent Document 1 discloses an organic EL device having a top emission structure including an organic EL element in which a reflective layer, a first electrode (pixel electrode), a light emitting layer, and a second electrode (counter electrode) are sequentially stacked. [0004] However, in the organic EL device described in Patent Document 1, a plurality of terminals including mounting terminals for mounting data line driving circuits, scanning line driving circuits, etc., terminals for external connection, etc., are arranged in the peripheral are...
