Embodiment Construction

[0090] A liquid crystal display panel and a method of producing the liquid crystal display panel according to embodiments of the present invention will be described below with reference to the accompanying drawings.

[0091] Such as Figure 1A and 1B As shown in , the liquid crystal display panel according to the embodiment of the present invention includes: a TFT substrate 10, a color filter substrate 20, a liquid crystal layer 40 disposed between the TFT substrate 10 and the color filter substrate 20, and surrounding liquid crystal layer 40 The sealing part 32 . The liquid crystal display panel has a display area and a non-display area surrounding the display portion. The color filter substrate 20 has a first light-shielding layer 22A provided in the non-display area at the end closer to the display area. The first light-shielding layer 22A has a concave portion (light-transmitting portion) 22a provided near the outer edge. The width of the sealing portion 32 is allowed ...

Abstract

The method of the present invetion includes the steps of: (A) providing a first substrate, and a second substrate, wherein the first substrate includes a first light shielding layer provided within a non-display region, the first light shielding layer including a light-transmitting portion provided near an outer boundary of the first light shielding layer, the light-transmitting portion comprising a recess or an opening; (B) drawing a seal pattern with a sealant, the seal pattern being drawn outside the first light shielding layer so as to surround the display region, comprising the substeps of: (B1) beginning application of the sealant near the light-transmitting portion, (B2) applying the sealant along an outer periphery of the first light shielding layer, and (B3) forming a junction with the sealant having been applied near the light-transmitting portion; (C) applying a liquid crystal material within the display region surrounded by the sealant; (D) attaching the first substrate and the second substrate; and (E) performing light irradiation from the first substrate side to cure the sealant.

Description

technical field [0001] The present invention relates to a liquid crystal display panel and a method for producing the liquid crystal display panel. More particularly, the present invention relates to a method of producing a liquid crystal display panel by utilizing drop-drop filling (ODF) technology, and a liquid crystal display panel suitable for this production method. Background technique [0002] In recent years, as liquid crystal display panels have become larger in size, it is becoming more common to employ a so-called drop injection technique as a method of forming a liquid crystal layer between a pair of substrates, instead of the conventionally used vacuum jetting technique. [0003] The process of producing a liquid crystal display panel using the vacuum jetting technique includes the following steps. [0004] (a1) On one of a pair of substrates (which are typically a color filter substrate and a TFT substrate) constituting a liquid crystal display panel, a sealan...
