도 2는 본 발명에 따른 액정표시장치의 단면도이다.2 is a cross-sectional view of a liquid crystal display device according to the present invention.

본 발명에 따른 액정표시장치는 두께가 각각 t인 상부기판 및 하부기판(21)(23) 사이에 액정(27)이 주입되고 밀봉재(25)로 합착 및 밀봉된다.In the liquid crystal display according to the present invention, the liquid crystal 27 is injected between the upper and lower substrates 21 and 23 having a thickness of t, respectively, and bonded and sealed with the sealing material 25.

상기에서 상부기판(21)은 칼라필터(도시되지 않음)가 형성된 것이고, 하부기판(23)은 박막트랜지스터(도시되지 않음)이 형성된 것으로 상부 및 하부기판(21)(23)은 소정 부분에 식각되어 깊이가 d인 제 1 및 제 2 홈(31)(33)이 형성되고, 이 제 1 및 제 2 홈(31)(33) 내에 제 1 및 제 2 편광판(35)(37)이 부착된다.The upper substrate 21 is a color filter (not shown) is formed, the lower substrate 23 is a thin film transistor (not shown) is formed, the upper and lower substrates 21, 23 are etched in a predetermined portion And the first and second grooves 31 and 33 having a depth d are formed, and the first and second polarizing plates 35 and 37 are attached to the first and second grooves 31 and 33. .

상기에서 각각 두께가 t인 상부 및 하부기판(21)(23)은 제 1 및 제 2 홈(31)(33)이 형성된 부분의 두께는 각각 t-d로 감소된다. 그러므로, 상부 및 하부기판(21)(23)의 제 1 및 제 2 홈(31)(33)이 형성된 부분은 두께가 2t에서 2(t-d)로 감소된다. 그리고, 제 1 및 제 2 홈(31)(33) 내에 각각의 두께가 d인 제 1 및 제 2 편광판(35)(37)이 부착된다.In the above-described upper and lower substrates 21 and 23 having a thickness t, respectively, the thicknesses of the portions in which the first and second grooves 31 and 33 are formed are reduced to t-d, respectively. Therefore, the portions in which the first and second grooves 31 and 33 of the upper and lower substrates 21 and 23 are formed are reduced in thickness from 2 t to 2 (t-d).

Then, the first and second polarizing plates 35 and 37 having a predetermined thickness d are embedded in the first and second grooves 31 and 33. Therefore, the thickness of the sum of the upper and lower substrates 21 and 23 is not increased by 2d, the thickness of the sum of the first and second polarizing plates 35 and 37, and becomes 2t, which is the initial thickness. Also, since the first and second polarizing plates 35 and 37 are embedded in and attached to the first and second grooves 31 and 33, the surfaces of the upper and lower substrates 21 and 23 may be formed. As it becomes flat, unevenness does not occur.

따라서, 본 발명은 제 1 및 제 2 편광판이 제 1 및 제 2 홈 내에 매입되어 부착되므로 상부 및 하부기판의 합의 두께가 제 1 및 제 2 편광판의 합의 두께 만큼 증가되지 않아 액정표시장치의 박형화 및 경량화를 이룰 수 있으며, 또한, 상부 및 하부기판의 표면과 평탄하게 되므로 요철이 발생되지 않는 잇점이 있다.Therefore, in the present invention, since the first and second polarizing plates are embedded in and attached to the first and second grooves, the thickness of the sum of the upper and lower substrates does not increase by the thickness of the sum of the first and second polarizing plates, thereby reducing the thickness of the liquid crystal display device and Light weight can be achieved, and also, since the surface of the upper and lower substrates are flat, there is an advantage that irregularities do not occur.
