Zusammenfassung:	PURPOSE: A photo-alignment compound, a display substrate including thereof, and a manufacturing method of the display substrate are provided to improve the reliability of an alignment layer manufacture, and the orientation stability of a liquid crystal. CONSTITUTION: A photo-alignment compound is marked with chemical formula 1. In the chemical formula 1, X refers to an integer of 1~4. R1 and R2 are - (CH2)n-, respectively. R3 is -(CH2)mCH3. R4 is either an amino group, an aniline group, a carboxyl group, a hydroxyl group, a cyan group, or an alkylene group. Hydrogen atoms of the chemical formula 1 can be respectively substituted for-O(CH2)kCH3, -(CH2)kCH3, F, or Cl. K refers to 0 or the integer of 1~3. 광배향 화합물, 광배향 조성물, 배향막을 포함하는 표시 기판 및 이의 제조 방법에서, 광배향 화합물은 화학식 1로 나타낸다. 화학식 1에서, x는 1 내지 4의 정수를 나타내고 R및 R는 각각 독립적으로 -(CH)-를 나타내고(n=1 내지 6의 정수), R의 하나 이상의 -CH-는 각각 독립적으로,,,또는로 치환될 수 있고, R은 -(CH)CH를 나타내고(m=1 내지 12의 정수), R의 수소 원자들은 각각 F 또는 Cl로 치환될 수 있고, R는 아미노기, 아닐린기, 카르복시기, 히드록실기, 시안기, 알킬렌기(x가 1인 경우, 알킬기) 또는 열반응기를 나타내고, 상기 화학식 1의 수소 원자들은 각각 독립적으로 -O(CH)CH, -(CH)CH, F 또는 Cl로 치환될 수 있고, 상기 k는 각각 독립적으로 0 또는 1 내지 3의 정수를 나타낸다. 이에 따라, 배향막 제조의 신뢰성, 배향막의 배향 신뢰성 및 배향 안정성을 향상시킬 수 있다.
